India & Its Neighbours — Bilateral Relations, Disputes & Cooperation

Overview — India's Neighbourhood Policy

India shares land or maritime borders with seven neighbours — Pakistan, China, Nepal, Bhutan, Bangladesh, Myanmar, and Sri Lanka — plus Afghanistan and the Maldives as extended neighbours. Managing these relationships is central to India's foreign policy and a high-priority topic for UPSC GS Paper 2.

Neighbourhood First Policy

Launched as a formal doctrinal approach in 2008 and elevated after 2014, the Neighbourhood First Policy is guided by the principles of respect, dialogue, peace, and prosperity. It is consultative, non-reciprocal, and outcome-focused, aiming to enhance physical, digital, and people-to-people connectivity, augment trade, and build a secure and stable neighbourhood.

Gujral Doctrine (1996)

Articulated by I.K. Gujral at Chatham House, London, in September 1996, this doctrine laid down five principles for relations with India's smaller neighbours:

1. India does not ask for reciprocity from neighbours like Nepal, Bangladesh, Bhutan, Maldives, and Sri Lanka — it gives in good faith and trust.
2. No South Asian country will allow its territory to be used against the interest of another.
3. None will interfere in the internal affairs of another.
4. All will respect each other's territorial integrity and sovereignty.
5. All disputes will be settled through peaceful bilateral negotiations.

Exam Tip: The Gujral Doctrine explicitly excluded Pakistan and China from its non-reciprocal framework. UPSC has asked about the doctrine's relevance — always note this critical exclusion and contrast it with the broader Neighbourhood First Policy which includes all neighbours.

India-China Relations

The Boundary Question

India and China share a ~3,488 km border (the LAC) that has never been formally demarcated. The dispute spans three sectors:

The Line of Actual Control (LAC) gained legal recognition in Sino-Indian agreements signed in 1993 and 1996. Unlike the LoC with Pakistan, the LAC is not demarcated on the ground, leading to differing perceptions of where it lies.

Key Events Timeline

Trade and Strategic Competition

India's trade deficit with China was a record USD 112.16 billion in FY 2025-26 — imports of USD 131.63 billion (up 16 per cent) against exports of USD 19.47 billion (up 36.66 per cent), on commerce ministry provisional data released in April 2026. The FY 2024-25 deficit was USD 99.2 billion. Bilateral trade of USD 151.1 billion made China India's largest trading partner in FY 2025-26, displacing the United States, which had held the position for four consecutive years to FY 2024-25; China had also been India's top partner from 2013-14 to 2017-18 and in 2020-21. The volume is a source of strategic vulnerability as much as of strength — India imports electronics, machinery, APIs (Active Pharmaceutical Ingredients), solar cells, and batteries from China.

String of Pearls vs Necklace of Diamonds:

• String of Pearls (coined 2004, US researchers) — China's network of military and commercial facilities along sea lines from Chinese mainland to the Horn of Africa, including ports at Gwadar (Pakistan), Hambantota (Sri Lanka), and Chittagong (Bangladesh).
• Necklace of Diamonds — India's counter-strategy involving port access and military partnerships at Chabahar (Iran), Duqm (Oman), Assumption Island (Seychelles), Agalega (Mauritius), and Changi Naval Base (Singapore).

India-Pakistan Relations

Kashmir — The Core Dispute

The Kashmir issue has defined India-Pakistan relations since Partition (1947). India holds it as an integral part of its territory (accession by Maharaja Hari Singh on 26 October 1947), while Pakistan terms it a disputed territory pending a UN plebiscite (UNSC Resolutions 39 and 47 of 1948).

Landmark Agreements

Indus Waters Treaty (1960)

Brokered by the World Bank, signed on 19 September 1960 in Karachi by PM Nehru and President Ayub Khan. It allocated the three eastern rivers (Ravi, Beas, Sutlej) to India and three western rivers (Indus, Jhelum, Chenab) to Pakistan. India issued modification notices in 2023 and 2024 citing demographic and environmental changes.

Following the Pahalgam terror attack in April 2025, India placed the treaty in abeyance on 23 April 2025 (MEA's own term is "in abeyance", not "suspension"), citing state-sponsored terrorism, and halted flow on the Chenab from the Baglihar Dam. It was the first such step in a treaty that had survived four wars in 65 years. Home Minister Amit Shah said on 21 June 2025 that the treaty would never be restored, adding that water which had flowed to Pakistan would be taken to Rajasthan by canal.

The Treaty before the Court of Arbitration

The Court of Arbitration constituted in the Kishenganga and Ratle dispute, for which the Permanent Court of Arbitration acts as registry, has ruled steadily against India's position across a chain of decisions: the Award on Competence (6 July 2023); a Supplemental Award on Competence (27 June 2025) holding that India's abeyance decision does not limit the Court's competence; the Award on Issues of General Interpretation (8 August 2025); a Decision on Pakistan's Request for Clarification (8 November 2025); and the Award Concerning Maximum Pondage (15 May 2026).

The decisive ruling came on 31 August 2026, after a hearing at the Peace Palace from 26 to 28 April 2026 held without Indian participation. In its Award on the Status of the Indus Waters Treaty, the Court held unanimously that "abeyance" could only amount to a claim that the Treaty is suspended or terminated, that none of the grounds India had cited could justify either, and that the Treaty therefore "remains fully in force", with India bound to observe its obligations, including those on the design and operation of its hydroelectric projects on the Western Rivers. The same day, in an Order on Interim Measures on Pakistan's application of 4 March 2026, the Court barred India from concreting the Ratle dam wall and power-intake structure above specified levels until 90 days after the Neutral Expert's final decision, expected in July 2027, and imposed a reporting measure on the project's construction schedule; two other Pakistani requests were declined. India, which has not participated in the proceedings, rejects the Court's jurisdiction and rejected the award the same day as the product of an illegally constituted body. The examinable tension is between treaty law and a sovereign security decision: the ruling is authoritative on paper and unenforceable in practice, and India's position is unchanged by it.

The 2025 Crisis — Pahalgam, Operation Sindoor and the Ceasefire

The April–May 2025 India-Pakistan crisis, triggered by the Pahalgam attack (22 April 2025, 26 killed, TRF/LeT perpetrators) and India's subsequent Operation Sindoor (6–7 May 2025, 24-minute precision tri-service strike on 9 terrorist camps: 5 in PoK + 4 in Pakistan's Punjab), represented the most significant military escalation between the two nuclear-armed neighbours since the 1999 Kargil War. A ceasefire was reached via the DGMO hotline on 10 May 2025. The 87-hour conflict fundamentally redefined India's deterrence posture and its tolerance for Pakistan-sponsored terrorism.

Pakistan used Chinese-origin weapons (J-10CE, PL-15E, CM-400AKG) extensively during the conflict. On the Indian side, SCALP cruise missiles used in Operation Sindoor led to negotiations with France for an additional order worth about EUR 300 million (roughly Rs 3,200 crore); as of 22 September 2026 the two sides remain in talks, no contract has been signed, and the deal did not feature among the outcomes of President Macron's visit of 17–19 February 2026 (ANI, 8 February 2026; Times of India, 9 February 2026).

Post-Conflict Contacts and Back-channels

Four back-channel meetings are on record since the May 2025 conflict: London (July 2025) and Muscat (October 2025), both Track 1.5 and facilitated by the International Institute for Strategic Studies; Thailand (December 2025), a Track 2 round under "The Chao Track", formerly the Chaophraya Dialogue; and Doha (February 2026), Track 2, facilitated by a UK-based think tank (Hindustan Times, 17 April 2026). Pakistan sent serving military officials to the London round; India sent no serving officials. Foreign Secretary Vikram Misri said on 29 June 2026, responding to reports of a Track 2 held on the sidelines of a regional security conference in Colombo, that such gatherings are "private events organised by private parties", with nothing official about them and no Indian participation, support or involvement. For an exam answer the caveat is the point: Track 2 is not state-to-state dialogue, and citing these meetings as evidence of a thaw without Misri's disclaimer is an error.

The LoC ceasefire has held in broad terms. On 31 December 2025, on the sidelines of Khaleda Zia's funeral in Dhaka, EAM S. Jaishankar walked over and shook hands with Sardar Ayaz Sadiq, Speaker of Pakistan's National Assembly, the first direct interaction between senior Indian and Pakistani officials since the May 2025 conflict, confined to brief pleasantries with no formal talks.

Trade Suspension

Pakistan formally suspended bilateral trade with India on 9 August 2019 in response to the revocation of Article 370 on 5 August 2019. Prior to suspension, India's exports to Pakistan stood at ~$2 billion (FY 2018-19). Limited exceptions exist for pharmaceuticals and essential items.

Key Distinction: The Shimla Agreement (1972) established the principle of bilateralism — disputes to be settled bilaterally, not through third-party mediation. India cites this to reject any international or UN mediation on Kashmir. Pakistan, however, invokes pre-Shimla UNSC resolutions. This is a frequently tested distinction in UPSC Mains.

India-Bangladesh Relations

Land Boundary Agreement (2015) — 100th Constitutional Amendment

The India-Bangladesh LBA, originally signed in 1974, was ratified through the 100th Constitutional Amendment Act (28 May 2015). Under it:

• India received 51 Bangladeshi enclaves (7,110 acres) inside Indian mainland
• Bangladesh received 111 Indian enclaves (17,160 acres) inside Bangladesh
• The remaining 6.1 km of undemarcated border was settled
• Enclave exchange executed at midnight on 31 July 2015
• The First Schedule of the Constitution was amended to adjust territories of Assam, West Bengal, Meghalaya, and Tripura

Water Disputes

The 1996 sharing formula works off availability at Farakka: below 70,000 cusecs each side receives roughly 50 per cent; above 75,000 cusecs India draws about 40,000 cusecs and the balance goes to Bangladesh; and between 11 March and 10 May each side is guaranteed 35,000 cusecs in three alternating ten-day periods. India maintains that Farakka is a diversion structure, not a dam, channelling about 40,000 cusecs into the Farakka feeder canal. Bangladesh's stated negotiating ask, set out by Water Resources Minister Shahiduddin Chowdhury Anee at a seminar in Dhaka and reported on 19 August 2026, is the restoration of the "guarantee clause" that the 1977 Ganges agreement carried and the 1996 treaty dropped, plus a right-to-information provision, with a stated readiness to approach international forums. MEA had framed the question on 2 June 2026 as part of structured collaboration across the 54 shared rivers, and in July 2026 India's parliamentary standing committee on external affairs urged the government to begin talks without further delay, guided by updated hydrological data, climate projections and the concerns of West Bengal and Bihar.

Other Key Issues

• Rohingya crisis — Over 1 million Rohingya refugees in Bangladesh; India has provided humanitarian aid but opposes taking refugees citing security concerns
• Connectivity — Maitri Setu (1.9 km bridge over Feni River) inaugurated 9 March 2021, linking Sabroom (Tripura) to Ramgarh (Bangladesh)
• Energy supply — Diesel reaches northern Bangladesh through the India-Bangladesh Friendship Pipeline in phased consignments, 22,000 tonnes across four phases by end-March 2026 (Network Bangladesh, 29 March 2026). Dhaka has since sought higher volumes of diesel and fertiliser, and Petroleum Minister Hardeep Singh Puri said in April 2026 that the request would be considered "readily and favourably"

Political Transition (2024–26)

PM Sheikh Hasina resigned on 5 August 2024 amid mass student protests (1,400+ killed in the crackdown, per UN estimates) after governing Bangladesh since 2009, and flew to India, landing at Hindan Air Force Base, Ghaziabad, where she was received by NSA Ajit Doval. Nobel laureate Muhammad Yunus assumed leadership of an interim government on 8 August 2024 and held office until February 2026.

Relations deteriorated sharply during the Yunus interregnum. Bangladesh requested Hasina's extradition in November 2025 under the 2013 bilateral extradition treaty, which India has not acted on, and its International Crimes Tribunal convicted her in absentia of crimes against humanity and sentenced her to death in November 2025. Attacks on Hindu minorities and temples drew Indian protest, with Bangladesh's high commissioner summoned twice within a fortnight in mid-2025, and India temporarily suspended visa services at its missions in Rajshahi and Khulna; ties reached their lowest point since the 1975 Mujib assassination. During his March 2025 China visit, Yunus described India's northeastern states as "landlocked" and Bangladesh as their "guardian of the ocean", remarks widely seen as a geopolitical provocation.

Former Prime Minister Khaleda Zia died in a Dhaka hospital on 30 December 2025, aged 80. Bangladesh declared three days of state mourning, and EAM S. Jaishankar travelled to Dhaka for the funeral on 31 December 2025, handing PM Modi's condolence letter to her son, BNP leader Tarique Rahman (NewsOnAir, 30 December 2025; The Statesman, 31 December 2025). Six weeks later, in the 12 February 2026 election, the BNP won 209 seats and Jamaat-e-Islami 68 on results declared for 297 constituencies of a 300-seat general House, the BNP polling about 49.97 per cent of the vote and Jamaat about 31.76 per cent; a constitutional referendum was held alongside (The Daily Star, February 2026). Tarique Rahman was sworn in as Prime Minister on 17 February 2026 (NewsOnAir, 17 February 2026).

Foreign Minister Khalilur Rahman made the new government's first ministerial visit to New Delhi on a two-day stop-over on 7–8 April 2026, en route to the 9th Indian Ocean Conference in Mauritius, holding talks with EAM Jaishankar on 8 April and meeting NSA Ajit Doval. Dhaka publicly reiterated its demand for Sheikh Hasina's extradition, which India has not acted on, while simultaneously asking for more Indian energy.

India-Sri Lanka Relations

Ethnic Conflict Legacy

The 1983-2009 Sri Lankan civil war between the government and LTTE had deep implications for India. India's IPKF (Indian Peace Keeping Force, 1987-90) and the assassination of PM Rajiv Gandhi (1991) remain sensitive legacies.

Key Bilateral Issues

Economic Recovery and the AKD Presidency (2024–26)

Sri Lanka completed IMF-supervised economic reforms following its 2022 debt crisis, in which India's USD 4 billion assistance package of credit lines and currency swaps proved critical in stabilising the economy. The September 2024 presidential election brought Anura Kumara Dissanayake (AKD) to power, the first left-wing, non-mainstream candidate since independence. He visited India in December 2024 for his first bilateral summit; the joint statement showed continuity on the core partnership agenda, agreed the comprehensive Digital Public Infrastructure (DPI) partnership, and prioritised the Colombo Port City and the Trincomalee energy hub. His government also indicated it would scrutinise Adani-linked wind farm deals awarded without competitive tender, reflecting domestic pressure on perceived Indian dominance.

PM Modi met President Anura Kumara Disanayaka in New Delhi on 20 February 2026, on the sidelines of the India-AI Impact Summit, the President's second visit to India after his December 2024 State Visit. They reviewed follow-up from PM Modi's April 2025 visit to Colombo, committed to accelerating physical, digital and energy connectivity, and exchanged views on artificial intelligence. Disanayaka thanked India for its relief after Cyclone Ditwah under Operation Sagar Bandhu, and both sides noted progress on India's USD 450 million assistance package; they also welcomed the exposition of the Holy Devnimori relics in Sri Lanka (MEA, 20 February 2026).

The August 2026 Assistance Package

Foreign Secretary Vikram Misri visited Sri Lanka on 5 August 2026, his first standalone visit in that capacity, calling on President Disanayaka, PM Harini Amarasuriya and Foreign Minister Vijitha Herath. The visit concluded agreements on two INR-denominated Lines of Credit, USD 250 million for railway projects and USD 100 million for livestock and other priority requirements, and recorded a USD 100 million grant for Cyclone Ditwah reconstruction of houses and bridges, work on which was to commence shortly, and the completion of a USD 5 million grant for rehabilitation of the Northern Railway corridor, on which services have resumed. On Kankesanthurai harbour, the two sides directed that discussions be initiated at the earliest to conclude an MoU, the project to be implemented under a USD 61.5 million grant. They discussed expediting energy projects including the electricity grid interconnection project, the Sampur solar power project and the development of Trincomalee as an energy hub. India pressed for the early release of detained Indian fishermen and their boats, and called on Sri Lanka to hold Provincial Council elections at the earliest and to implement fully the constitutional provisions addressing Tamil aspirations, which is the 13th Amendment question in its current form (MEA readout, 5 August 2026). Separately, on 4 August 2026, India's High Commissioner Santosh Jha handed over 500 litres of Technical Malathion for dengue control to Health and Mass Media Minister Dr Nalinda Jayatissa.

India-Nepal Relations

1950 Treaty of Peace and Friendship

Signed on 31 July 1950, this treaty established an open border regime allowing free movement of people and goods, and granted Nepali nationals the right to work in India and vice versa. Nepal has repeatedly sought its revision, viewing it as unequal.

Kalapani-Lipulekh-Limpiyadhura Dispute

The border dispute centres on the origin of the Kali (Mahakali) River, which defines Nepal's western boundary per the Sugauli Treaty of 1815:

• India's position: Kali originates at Lipulekh; Kalapani is Indian territory
• Nepal's position: Kali originates at Limpiyadhura, further northwest; all territory east of it (including Kalapani and Lipulekh) is Nepali

In May 2020, after India inaugurated a road to Lipulekh Pass (for Kailash Mansarovar pilgrimage), Nepal released a new political map claiming Kalapani, Lipulekh, and Limpiyadhura. Nepal's parliament passed a constitutional amendment to formalise the new map, leading to a temporary diplomatic breakdown. The dispute remains unresolved and is now front and centre under the Balendra Shah government's assertive foreign policy stance, which produced a fresh formal protest over the Lipulekh route in May 2026.

Other Issues

• Hydropower and power trade — Joint projects on the Mahakali River; Upper Karnali and Arun-III under development, with SJVN also developing the roughly 670 MW Lower Arun. Physical progress on the generation component of the 900 MW Arun-III (SJVN) was reported at about 74.6 per cent in January 2026, with the cross-border transmission line to Sitamarhi at about 58 per cent; commissioning has slipped repeatedly from the original March 2025 target and the developer has applied to extend the Commercial Operation Date (Nepal Energy Forum, January 2026). The 480 MW Upper Tamakoshi project is operational. Nepal exported about 1,100 MW of electricity to India in the year to mid-2026 and also supplies Bangladesh through the Indian grid; the 2014 Power Trade Agreement envisages eventual export of 10,000 MW to India (MEA brief, July 2026)
• Grid connectivity — The high-capacity Muzaffarpur–Dhalkebar line is operational and Gorakhpur–Butwal is at an advanced stage; joint-venture agreements have been signed for two further cross-border lines, Dododhara–Bareilly and Inaruwa–Purnea, and three 132 kV cross-border lines were inaugurated in 2024
• Trade and investment — India-Nepal goods trade was about US$ 9.38 billion in FY 2025-26, more than 60 per cent of Nepal's total external goods trade, with India taking over 80 per cent of Nepal's goods exports. India is the largest source of FDI in Nepal, roughly one-third of the total, with estimated Indian investment of about US$ 800 million across some 150 ventures. India has extended Lines of Credit worth US$ 750 million since 2006; the 11th LoC Review Meeting was held in New Delhi on 4 December 2025 (MEA brief, July 2026)
• Digital and legal cooperation — The peer-to-peer linkage between India's UPI and Nepal's National Payments Interface (NPI) for cross-border personal remittances was launched in June 2026, alongside a Digital India Bhashini–Kathmandu University MoU for a "Voice First" translation platform; an Agreement on Mutual Legal Assistance in Criminal Matters was signed in February 2026 to strengthen investigation and prosecution of cross-border crime
• Grant assistance — India gifted about 650 vehicles for the 5 March 2026 elections, part of more than 3,000 gifted to Nepali institutions over the years, and is providing ten bridges of 70-metre and higher span in eastern Nepal on a grant basis after the heavy rains of October 2025 (MEA brief, July 2026)
• Agnipath Scheme — Nepal raised concerns about the impact on Gorkha recruitment into the Indian Army

Political Change and Bilateral Friction (2025–26)

KP Sharma Oli became PM for a fourth time in July 2024, in coalition with the Nepali Congress. His government imposed a social media ban in September 2025, triggering Gen Z-led mass anti-corruption protests; police opened fire on demonstrators, death toll estimates range from 19 (initial reports) to 77 (broader September 2025 unrest) across multiple incidents, and parliament was set on fire. Oli resigned on September 9, 2025 (Kathmandu Post, Al Jazeera, September 2025). Former Chief Justice Sushila Karki was appointed caretaker PM on September 12, 2025 to lead an interim government until elections. In the 5 March 2026 general election, the Rastriya Swatantra Party (RSP) under rapper-turned-politician Balendra Shah ("Balen") won a landslide, 182 of 275 seats, defeating all established parties, and Balendra Shah was sworn in as Prime Minister on 27 March 2026.

On 28 March 2026, the day after the swearing-in, Nepal Police arrested former PM K.P. Sharma Oli, 74, at his home and former Home Minister Ramesh Lekhak, 62, after a panel appointed to investigate the September 2025 unrest recommended that both be prosecuted for criminal negligence; neither had been charged at the time. Oli was taken to a Kathmandu clinic as routine police procedure. The CPN-UML launched nationwide protests; the new Home Minister, Sudan Gurung, himself a leading figure in the Gen Z protests, welcomed the arrests. The BBC's account of the crackdown records more than 70 deaths overall, at least 19 of them on 8 September 2025, with the families of 76 people seeking accountability (BBC, 28 March 2026).

PM Modi invited Shah to India in his congratulatory message, but the opening weeks were difficult. Shah's office had decided, during the transition weeks before his swearing-in, that he would not hold bilateral meetings with foreign officials below the rank of head of government or minister; he met 17 ambassadors jointly at Singhadurbar on 8 April 2026 instead. Nepal began strictly enforcing customs duty on goods brought from India worth more than Rs 100 from mid-April 2026, disrupting everyday border commerce. Indian Foreign Secretary Vikram Misri's visit, tentatively scheduled for 11 May 2026, was postponed. Above all, after MEA announced on 30 April 2026 that the 2026 Kailash Mansarovar Yatra would run from June to August with one route through Lipulekh Pass, Nepal's Foreign Ministry issued a formal diplomatic protest to both India and China on 3 May 2026, calling Limpiyadhura, Lipulekh and Kalapani integral parts of Nepal since the Sugauli Treaty (Kathmandu Post, 20 May 2026).

Re-engagement followed quickly. Nepal's Foreign Minister Shisir Khanal visited India from 5 to 7 June 2026 at EAM Jaishankar's invitation, to discuss trade, investment, connectivity, energy and people-to-people ties; he had already met the EAM on the sidelines of the 9th Indian Ocean Conference at Port Louis on 10 April 2026. MEA's bilateral brief records three ministerial visits from India to Nepal and five from Nepal to India in FY 2025-26, evidence that the working relationship continued through the political noise.

India-Bhutan Relations — The Model Partnership

India-Bhutan relations are often cited as a model bilateral relationship in South Asia.

Treaty Evolution

The 1949 Treaty of Friendship and Cooperation guided Bhutan's foreign relations through India. It was replaced by the 2007 India-Bhutan Friendship Treaty, which gave Bhutan full autonomy in foreign policy while maintaining close bilateral cooperation — a modernisation ahead of Bhutan's transition to democracy in 2008.

Hydropower — The Backbone

Punatsangchhu-II began exporting surplus power to India on 19 September 2025 at a mutually agreed starting tariff and was jointly inaugurated by His Majesty the King of Bhutan and PM Modi on 11 November 2025; a Protocol to the bilateral agreement fixing its export tariff was signed on 9 April 2026. Work on the main dam structure of Punatsangchhu-I, stalled since 2019 over geological problems, restarted with a first concrete pour ceremony on 10 April 2026 attended by Union Power Minister Manohar Lal and Bhutan's Energy and Natural Resources Minister; once complete it will be the largest hydroelectric project jointly developed by the two governments.

Bhutan does not have formal diplomatic relations with China. India remains Bhutan's largest aid donor and trading partner. The Doklam standoff (2017) underscored India's security commitment to Bhutan.

Bhutan-China boundary talks: The 15th Expert Group Meeting on Bhutan-China Boundary Issues was held in Beijing from 30 March to 1 April 2026, co-chaired by Bhutan's Secretary of International Boundaries, Letho Tobdhen Tangbi, and Hou Yanqi, Director General of China's Department of Boundary and Ocean Affairs. The two sides agreed to maintain the momentum of negotiations under the Three-Step Roadmap and to hold the next Expert Group Meeting in Bhutan; the 3rd meeting of the Joint Technical Team on Delimitation and Demarcation met on the sidelines to discuss alignment in areas where there is no dispute. The India-China August 2025 agreement on an Expert Group under the WMCC for Early Harvest boundary delimitation creates a parallel opening on the India-China-Bhutan tri-junction, which requires trilateral coordination. The Doklam plateau remains sensitive, with continued Chinese military build-up in the Chumbi Valley (Source: ORF, 2025).

Mnemonic: Remember Bhutan hydropower projects in order of commissioning — "CKT-MP" — Chhukha (1986), Kurichhu (2001), Tala (2006), Mangdechhu (2019), Punatsangchhu-II (2025). Punatsangchhu-I is the one still under construction. This covers the entire arc of India-Bhutan hydropower cooperation.

Rail Links and the Wider Development Partnership

On 29 September 2025 India and Bhutan signed an MoU for the first cross-border rail links between the two countries: Kokrajhar–Gelephu, about 70 km (66.66 km in India, 2.39 km in Bhutan), to be built in four years, and Banarhat–Samtse, about 20 km (17.42 km in India, 2.13 km in Bhutan), in three years, at a combined envisaged investment of about Rs 4,033 crore for roughly 89 km of new railway, of which Banarhat–Samtse accounts for about Rs 577 crore. Segments on Indian territory are funded by the Ministry of Railways and those in Bhutan by MEA as part of India's support to Bhutan's 13th Five Year Plan; a Project Steering Committee was set up thereafter.

PM Modi's November 2025 state visit filled out the rest of the partnership: India's support for the King's Gelephu Mindfulness City vision and a decision to establish an Immigration Check Post at Hatisar, Assam; a concessional Line of Credit of INR 40 billion for energy projects; support to the 13th Five Year Plan including the Economic Stimulus Programme and the Gyalsung academies; institutionalised arrangements for uninterrupted supply of essential commodities and fertilisers, with the first consignment received; work on UPI Phase II to let Bhutanese visitors to India pay by scanning QR codes; and three MoUs, on renewable energy, on health and medicine, and between Bhutan's PEMA Secretariat and NIMHANS. The Darranga Immigration Check Post was operationalised in November 2024 and the Jogigopha Inland Waterways Terminal and Multimodal Logistics Park in March 2025.

India-Myanmar Relations

Act East Gateway

Myanmar is India's only ASEAN neighbour sharing a land border (1,643 km), making it the gateway for India's Act East Policy. The Kaladan Multi-Modal Transit Transport Project has three legs: a sea leg from Kolkata to Sittwe, a river leg of 158 km up the Kaladan from Sittwe to Paletwa in Chin State, and a road leg of 109 km from Paletwa to Zorinpui in Mizoram. The Sittwe terminal and the waterway component are complete and operational — the first cargo from Kolkata reached Sittwe in May 2023 — while the Paletwa–Zorinpui road is the final incomplete piece. Union Minister Sarbananda Sonowal told Parliament in July 2025 that the project would be fully operational by 2027, but construction is confined to a November–April dry window when local labour is scarce, and Paletwa township is contested between the Arakan Army and the Chinland Defence Force–Paletwa, with Chin groups opposing the Arakan Army's attempt to administer Paletwa as part of Rakhine (Source: The Diplomat, 12 February 2026).

Free Movement Regime (FMR) — Announced Scrapped, 2024

The FMR, established in 1968, allowed border tribes to travel up to 16 km inside the other country without a visa. Home Minister Amit Shah announced on 8 February 2024 that it would be scrapped, citing internal security and the demographic structure of the northeastern states. The formal notification is an MEA matter, because the FMR rests on a bilateral arrangement, and had still not been issued as of December 2024. In practice MHA replaced the regime with a stricter protocol from December 2024: movement only by residents within 10 km on either side (down from 16 km), through 43 designated entry and exit points, on a seven-day biometric, QR-coded border pass issued by the Assam Rifles, with the points to be made functional in phases. Nagaland's assembly passed a resolution against scrapping the FMR and Mizoram also objected.

Alongside this, the Cabinet Committee on Security gave in-principle approval on 18 September 2024 to fence the entire 1,643 km border and build a patrolling track, at about Rs 31,000 crore over roughly ten years. Execution has lagged far behind the decision: about 30 km of fencing had been completed as of March 2026, against 1,472 km of the border demarcated (Rajya Sabha intervention, March 2026).

Other Issues

• Chin refugees — Thousands of Chin people from Myanmar have sought refuge in Mizoram since the 2021 coup; India has provided humanitarian assistance
• NE insurgent camps — Myanmar-based insurgent groups (NSCN, ULFA) have historically operated from Myanmar territory; India conducts cross-border operations with Myanmar's consent

India-Maldives Relations

The "India Out" Campaign and Political Shift

President Mohamed Muizzu won the 2023 presidential election on a platform heavily influenced by the "India Out" campaign. Upon taking office (November 2023), he cancelled the hydrographic survey agreement with India (signed 2019, expired June 2024), asked India to withdraw its military personnel, and made China his first major bilateral partner.

2025 Reset

By 2025, relations underwent a significant course correction. Muizzu made a state visit to India in October 2024, formalising a comprehensive cooperation framework, and India provided critical financial support: a USD 50 million treasury bill rolled over (May 2024) and currency swap agreements worth USD 760 million (October 2024). PM Modi made a state visit to Maldives on 25–26 July 2025, attending the 60th Independence Day celebrations as the first Indian head of state to do so. Muizzu acknowledged India's pivotal role in managing the Maldives' economic and liquidity challenges, a marked departure from his "India Out" campaign rhetoric.

Key outcomes of the July 2025 visit (Source: MEA List of Outcomes, 25–26 July 2025; IDSA, Organiser, Gateway House, July–August 2025):

• India extended a Rs 4,850 crore (~USD 554 million) Line of Credit to Maldives
• An amendatory agreement reducing Maldives' annual debt repayment by 40% was signed
• India handed over 72 vehicles and other equipment and two BHISHM Health Cube sets; a new Ministry of Defence building in Malé was jointly inaugurated
• 3,300 social housing units in Hulhumalé, built under India's Buyers' Credit facilities, were handed over; the Addu city roads and drainage project and six High Impact Community Development Projects were inaugurated
• A commemorative stamp was issued jointly for 60 years of diplomatic relations
• Eight MoUs and agreements were exchanged, covering fisheries and aquaculture, IITM–Maldives Meteorological Services cooperation, population-scale digital solutions, Maldivian recognition of the Indian Pharmacopoeia, and the NPCI International (NIPL)–Maldives Monetary Authority network-to-network agreement on UPI
• The Terms of Reference for an India-Maldives FTA were exchanged, and the launch of FTA negotiations was recorded as an outcome in its own right

From Announcement to Execution (2026)

The inaugural round of India-Maldives FTA negotiations commenced on 29 June 2026 and ran to 7 July 2026 in virtual mode, with eight technical sessions across eight policy areas. The Maldives' Minister of Economic Development, Transport and Trade has said he expects the agreement to be concluded before the end of 2026; the joint formulation commits the two governments only to expediting its conclusion, alongside a Bilateral Investment Treaty. On 30 July 2026 the Maldives Monetary Authority announced the successful go-live of the integration between the Maldives Instant Payment System, "Favara", and India's UPI: transactions are initiated in Maldivian Rufiyaa and credited in Indian Rupees, the launch phase covering Bank of Maldives Plc and Maldives Islamic Bank Plc for person-to-person family-maintenance and gift remittances, with QR-based merchant payments planned in later phases (PIB, 31 July 2026). PIB lists UPI as accepted in nine countries: Cambodia, Singapore, UAE, France, Mauritius, Nepal, Bhutan, Qatar and Sri Lanka.

Common Mistake: Students often describe India-Maldives relations as permanently damaged post-2023. In reality, small-island economies have structural dependencies on India (proximity, trade, security). The 2025 reset demonstrates that geopolitics is cyclical, not linear. Always present both the friction and the reset in your answers for a balanced perspective.

India-Afghanistan Relations

Development Partnership

India invested over $3 billion in Afghanistan across major projects:

Post-Taliban 2021

After the Taliban takeover in August 2021, India adopted a "people-first diplomacy" approach:

• Sent ~50,000 MT of wheat, 300+ tonnes of medicines, COVID-19 vaccines, and earthquake relief
• Redeployed a technical team to the Kabul embassy in June 2022 to coordinate humanitarian aid
• Engaged Taliban officials diplomatically but has not formally recognised the Taliban government

Engagement Without Recognition (2025–26)

The pace of engagement changed sharply in late 2025. Taliban Foreign Minister Amir Khan Muttaqi visited India from 9 to 16 October 2025, the first visit to India by a senior figure of the Taliban government since 2021, and held talks with EAM S. Jaishankar. On 21 October 2025 MEA announced that India's Technical Mission in Kabul was being restored to full Embassy status with immediate effect. A Taliban-appointed Chargé d'Affaires took charge of the Afghan Embassy in New Delhi in January 2026. The economic track followed: the India-Afghanistan Joint Working Group on Trade, Commerce and Investment met virtually on 1 September 2026, covering trade facilitation and customs cooperation, visa facilitation for Afghan traders, banking and financial cooperation, pharmaceutical and agricultural trade, energy, investment promotion, tariff concessions and cargo connectivity, with follow-up agreed on customs and data-sharing and on regulatory cooperation in pharmaceuticals and agriculture (PIB, 2 September 2026).

India has still not formally recognised the Taliban government. The sequence is therefore the standard UPSC illustration of de facto engagement without de jure recognition: upgrade the mission, accept an accredited representative, institutionalise trade talks, and withhold recognition.

What Changed in 2024–26

Four of India's neighbours changed government inside two years, and the pattern that emerges is the examinable one: India's leverage held wherever something physical or financial had been built before the change, and thinned wherever the relationship rested on a single leader, or on a negotiation that had never opened.

Bangladesh moved from a partner government to a hostile interregnum and back to a workable one. Hasina's fall in August 2024 removed the single relationship on which India's eastern policy had rested since 2009, and the Yunus period that followed was the lowest point since 1975: an extradition demand India would not meet, a death sentence passed in absentia, violence against minorities, and a deliberate reminder from Dhaka in March 2025 that India's northeast depends on Bangladeshi access to the sea. Jaishankar's decision to attend Khaleda Zia's funeral on 31 December 2025, weeks before an election, was a low-cost bet on whoever won it, and it paid off when Tarique Rahman's foreign minister came to Delhi in April 2026 carrying a hard political ask and a pragmatic economic one in the same visit. That combination defines the relationship's present shape, and it is why the Ganga Waters Treaty is now the real test: an expiry date fixed since 1996, a Bangladeshi request for talks left unanswered, and India's own parliamentary committee urging the government to begin. Whether a treaty framework survives a change of government on the other side, when the negotiation itself never opened, is the question worth arguing in an answer.

Pakistan is the mirror image, where everything changed operationally and nothing changed diplomatically. Pahalgam and Operation Sindoor reset India's declared tolerance for cross-border terrorism, and holding the Indus Waters Treaty in abeyance carried the crisis into an instrument that had survived four wars. The Court of Arbitration's award of 31 August 2026 is where the exam value sits, because it sets treaty law against a sovereign security decision India will not revisit. The back-channel meetings reported since 2025 are the trap: the Government of India disowns them, and Misri said so on 29 June 2026, so they evidence interest rather than a thaw. What to watch is the Neutral Expert's decision expected in July 2027, to which the Court's interim order on Ratle is pegged.

Nepal shows how fast a domestic rupture becomes a bilateral problem. The Gen Z protests of September 2025 ended Oli's fourth term, and the government that emerged in March 2026 under Balendra Shah is assertive by design rather than by accident: a protocol restricting ministerial meetings, stricter customs enforcement at the border, a postponed Foreign Secretary visit and, above all, the formal protest of 3 May 2026 over the Lipulekh route for the Kailash Mansarovar Yatra. Yet the working relationship held, and the payments linkage and the mutual legal assistance agreement both landed in the same window. Connectivity and finance now carry the relationship through political weather that would once have stalled it.

The Maldives and Sri Lanka are the demonstration cases for economic statecraft. Muizzu came to office on "India Out" and returned to cooperation because the Maldives' dependence on India is structural rather than sentimental, and what makes 2026 different from the 2025 reset is that live FTA negotiations and a working payments corridor are far harder for a future government to reverse than a communiqué. Sri Lanka's AKD, elected in September 2024 from outside the mainstream and widely expected to be difficult for Delhi, instead deepened the partnership, because India had been the first responder in the 2022 crisis and remained the reconstruction partner after Cyclone Ditwah. The instrument is the same in both cases, being credit, grants, payments rails and digital public infrastructure, and so is the constraint: the fishermen and the 13th Amendment in Colombo, domestic sensitivity about Indian dominance in Malé.

Afghanistan and Bhutan changed in the opposite direction, by accretion rather than by rupture. Kabul moved from a technical mission to an embassy, then to an accredited Chargé d'Affaires and an institutionalised trade working group, between October 2025 and September 2026, without recognition at any point, which is the cleanest available illustration of de facto engagement without de jure recognition. Bhutan converted a long-stalled hydropower relationship into a wider one covering rail, payments and city-scale projects, while its own boundary talks with China advanced at Beijing in March 2026 and India's parallel track opened under the WMCC. The tri-junction is where those two processes meet, and it is the thing to watch.

For Mains, the through-line is that Neighbourhood First was tested by regime change rather than by rivalry, and that China's footprint mattered less across 2024-26 than whether India's own commitments had been converted into working infrastructure before the government on the other side changed.

Vocabulary

Repudiate

• Pronunciation: /rɪˈpjuːdieɪt/
• Definition: To reject, deny, or refuse to accept or be associated with something — an opinion, accusation, agreement, debt, or person — as invalid, unjust, or without binding force. It conveys a firm, often public, disavowal stronger than mere disagreement.
• Root: Latin repudiāre = to divorce, cast off; re- = back/away + root linked to pudere = to feel shame; precise inner root uncertain
• Origin: From Latin repudiare 'to divorce, cast off, reject', from repudium 'a putting away, divorce', commonly analysed as re- 'back, away' + a root linked to pudere 'to feel shame' (the precise root being uncertain). Entered English in the 1540s, sense extended to disowning persons (1690s), opinions (1824), and debts (1837).
• Part of Speech: verb (transitive)
• Word Family: repudiation (n), repudiated (adj), repudiator (n), repudiable (adj)
• Usage: In its statement on the floor of the House, the government moved to repudiate the colonial-era sedition provisions, signalling that a mature constitutional democracy must disavow laws fundamentally at odds with the freedoms it claims to guarantee.
• Synonyms: reject, disavow, renounce, disown, spurn, abjure
• Antonyms: embrace, endorse, accept, affirm
• Mnemonic: Repudiate hides "pud-" from Latin pudere, "to shame" — to repudiate is to push something away in shame, refusing to own it.
• UPSC: To reject formally, or to refuse to be bound by an agreement or obligation. It is the precise verb in GS2 for a State disowning a commitment, and the distinction worth drawing is between repudiating an agreement, which denies its binding force, and withdrawing under a clause the agreement itself provides, which is lawful exit. The two have very different consequences for a State's reputation.
• Nuance: Repudiate refuses to be bound, denying the obligation. Withdraw exits through a procedure the agreement provides. Renounce formally gives up a claim or right. Abrogate is the annulment of an agreement, often by one party's act.
• Hindi: अस्वीकार करना (asvīkār karnā) or परित्याग करना.
• FAQ: What does repudiate mean? || To formally reject something, or to refuse to be bound by an agreement or obligation.
• FAQ: How does repudiating a treaty differ from withdrawing from one? || Withdrawal follows a procedure the treaty itself provides and is lawful. Repudiation denies the obligation's binding force, with much greater reputational cost.

Jingoism

• Pronunciation: /ˈdʒɪŋ.ɡəʊ.ɪ.zəm/
• Definition: Extreme, belligerent nationalism or chauvinism, especially as expressed through an aggressive, sabre-rattling foreign policy and a contemptuous attitude towards other nations.
• Root: Coined/Modern: English jingo (euphemistic oath, 1690s) + -ism; popularised by 1878 British music-hall song
• Origin: From English "jingo" + "-ism"; coined 1878 from the refrain of a British music-hall song ("we don't want to fight, but by Jingo if we do...") backing aggressive policy against Russia in the Russo-Turkish War. "Jingo" was a colloquial euphemistic oath (by jingo, 1690s), probably a minced form of "Jesus".
• Part of Speech: noun (uncountable)
• Word Family: jingo (n), jingoist (n), jingoistic (adj), jingoistically (adv)
• Usage: When statecraft surrenders to the television studio, sober diplomacy is too often drowned out by jingoism, as governments substitute the hard work of negotiation with theatrical displays of belligerence calculated to inflame, rather than inform, public opinion.
• Synonyms: chauvinism, ultranationalism, belligerent nationalism, super-patriotism, hawkishness, sabre-rattling
• Antonyms: internationalism, cosmopolitanism, pacifism, patriotism (moderate, reasoned)
• Mnemonic: Picture a crowd roaring "by JINGO, let's fight!" -- "jingo" was the war-cry of music-hall hotheads, so JINGOism = flag-waving spoiling for a fight.
• UPSC: Extreme and belligerent patriotism, especially in support of aggressive foreign policy. It names a specific pathology for GS2 and Essay: jingoism narrows the space for diplomacy by making compromise domestically costly, so a government that has encouraged it may find its own options constrained. That feedback from public mood to policy latitude is what makes it more than a term of abuse.
• Nuance: Jingoism is aggressive, belligerent patriotism. Patriotism is love of country without the aggression. Chauvinism asserts superiority, of a nation or any other group. Nationalism is the political claim to self-government, which need not be belligerent.
• Hindi: अंधराष्ट्रवाद (andhrāshtravād), literally blind nationalism.
• FAQ: What is jingoism? || Extreme and belligerent patriotism, particularly in support of aggressive foreign policy.
• FAQ: How does jingoism constrain foreign policy? || By making compromise politically costly at home, it narrows the room a government has to negotiate, sometimes limiting its own options.

Capitulate

• Pronunciation: /kəˈpɪtjʊleɪt/
• Definition: To surrender or cease resisting an opponent or demand, typically on agreed terms; to give in after a struggle. It stresses the complete ending of resistance, whether through negotiated terms or in the face of an irresistible force.
• Root: Medieval Latin capitulare = to draw up in chapters; Latin capitulum = chapter/heading; Latin caput = head
• Origin: From Medieval Latin capitulare 'to draw up in heads or chapters, arrange conditions', from capitulum 'chapter, heading' (diminutive of caput 'head'). Entered English in the 1590s meaning 'to draw up in articles', shifting to the sense 'surrender on stipulated terms' by the 1680s.
• Part of Speech: verb (intransitive)
• Word Family: capitulate (v), capitulated (v past), capitulating (v pres.p), capitulation (n), capitulatory (adj)
• Usage: When a government capitulates to every populist demand rather than upholding fiscal prudence, it mortgages long-term macroeconomic stability for fleeting electoral gains.
• Synonyms: surrender, submit, yield, succumb, concede, acquiesce
• Antonyms: resist, defy, persevere, withstand
• Mnemonic: Think "capital" + "ate" — a defeated city loses its CAPITAL when its leaders capitulate; or recall the Latin caput "head," as the vanquished bow their HEADS in surrender, signing terms chapter by chapter.
• UPSC: To surrender or cease resistance, usually on terms set by the other side. In GS2 it is a loaded word, so it should be used where an answer intends the judgement it carries: describing a settlement as capitulation asserts that one side simply gave way. Where the outcome was a negotiated trade-off, concede or compromise are the accurate words and a stronger answer uses them.
• Nuance: Capitulate is to surrender on the other side's terms. Concede grants a specific point within a negotiation. Compromise involves movement by both sides. Acquiesce accepts something passively without formal surrender.
• Hindi: आत्मसमर्पण करना (ātmasamarpan karnā).
• FAQ: What does capitulate mean? || To surrender or stop resisting, generally accepting terms set by the other party.
• FAQ: Is capitulation the same as compromise? || No. Compromise involves movement by both sides. Capitulation means one side gave way on terms the other set.

Truculent

• Pronunciation: /ˈtrʌk.jʊ.lənt/ (British) ; /ˈtrʌk.jə.lənt/ (American)
• Definition: Aggressively defiant, belligerent, or eager to argue; disposed to fight or behave in a hostile, scathingly harsh manner. Often applied to people, language, or attitudes that are confrontational and obstinate.
• Root: Latin truculentus = fierce, savage, cruel; trux (genitive trucis) = fierce, rough, wild; entered English 1530s
• Origin: From Latin truculentus 'fierce, savage, cruel', from trux (genitive trucis) 'fierce, rough, wild'; entered English in the 1530s.
• Part of Speech: adjective
• Word Family: truculently (adv), truculence (n), truculency (n), truculentness (n)
• Usage: When public institutions adopt a truculent posture towards every critic, branding dissent as sedition rather than engaging it, they corrode the very deliberative culture on which a constitutional democracy depends.
• Synonyms: belligerent, pugnacious, combative, aggressive, defiant, hostile
• Antonyms: conciliatory, amiable, docile, pacific
• Mnemonic: Picture a "truck" that aggressively bulldozes everything in its path -- TRUCk-ulent is a person who bullies and barges through like a belligerent truck, always spoiling for a fight.
• UPSC: Aggressively defiant and eager to fight. It is a strong characterisation, so in GS2 it should describe conduct that has been demonstrated rather than serve as a label for a State one disapproves of. Used precisely it captures posture rather than policy: a State may be truculent in rhetoric while remaining cautious in action, and noting that gap is often the more interesting analysis.
• Nuance: Truculent is aggressively defiant in manner. Belligerent is engaged in or eager for conflict, and in law denotes a party to an armed conflict. Assertive pursues interests firmly without hostility. Provocative is intended to elicit a reaction.
• Hindi: उग्र (ugra) or आक्रामक (ākrāmak).
• FAQ: What does truculent mean? || Aggressively defiant and eager to argue or fight.
• FAQ: Is truculent the same as assertive? || No. Assertive means pursuing one's interests firmly. Truculent adds hostility and a readiness to confront.

Intransigent

• Pronunciation: /ɪnˈtræn.sɪ.dʒənt/
• Definition: Refusing to compromise or to abandon an extreme position or attitude; unyielding and uncompromising, especially in negotiation or principle.
• Root: Latin transigere = to come to agreement; trans- = across; agere = to drive; in- = not
• Origin: First used in English in 1874, from French intransigeant, from Spanish los intransigentes ("those not coming to agreement", a name for extreme republicans in the 1870s), from in- "not" + Latin transigere "to come to an agreement", from trans- "across, through" + agere "to drive, carry through".
• Part of Speech: adjective; also noun
• Word Family: intransigence (n), intransigency (n), intransigently (adv), transigent (adj)
• Usage: When the two sides remained intransigent on the question of sharing river waters, the Union government's role shifted from neutral arbiter to active mediator, underscoring that cooperative federalism cannot function where states treat negotiation as surrender.
• Synonyms: uncompromising, obdurate, inflexible, unyielding, adamant, obstinate
• Antonyms: accommodating, flexible, conciliatory, compromising
• Mnemonic: In- ('not') + transigent (think 'transact / transaction') = one who will NOT transact, i.e. refuses to make a deal or strike a bargain.
• UPSC: Refusing to compromise or to change a position. It is a precise word for a negotiating posture, and its analytical value in GS2 is that intransigence is often strategic rather than temperamental: a party may refuse movement because it expects time to improve its position, or because domestic politics forecloses concession. Identifying which explains more is the useful move.
• Nuance: Intransigent refuses to compromise. Inflexible lacks capacity to adapt rather than willingness. Obdurate is stubbornly resistant to persuasion generally. Principled holds a position on grounds of value, which is the charitable reading of the same behaviour.
• Hindi: अड़ियल (adiyal) or समझौता न करने वाला.
• FAQ: What does intransigent mean? || Refusing to compromise or to alter one's position.
• FAQ: Why might a State be intransigent in negotiations? || Often for strategic reasons, such as expecting time to improve its position, or because domestic political constraints make concession impossible.

Bilateral

• Pronunciation: /ˌbaɪˈlæt.ər.əl/
• Definition: Involving or affecting two parties or sides, especially two nations, in a mutual agreement or negotiation.
• Root: Latin bi- (two) + latus (side) → lateralis (of the side) + -al; first used in English late 18th century.
• Origin: From Latin bi- ("two") + lateralis ("of or belonging to the side"), from latus ("side"); first used in English in the late 18th century.
• Part of Speech: adjective
• Word Family: bilateral (adj), bilaterally (adv), bilateralism (n), bilateralist (n), multilateral (adj)
• Usage: India's pursuit of strategic autonomy is reflected in its preference for resolving border disputes through bilateral dialogue rather than ceding space to third-party or multilateral arbitration.
• Synonyms: two-sided, reciprocal, mutual, two-way, dual, paired
• Antonyms: unilateral, multilateral, one-sided
• Mnemonic: Bi- (two) + lateral (side) = "two sides" — picture two nations sitting on opposite sides of one negotiating table.
• UPSC: Involving two parties, typically two States. In GS2 the useful framing is comparative: bilateral engagement allows tailored bargains and faster decisions, while multilateral forums confer broader legitimacy and bind more parties to a common rule. India's neighbourhood policy is largely bilateral in structure, and the reasons for that preference, including the ability to calibrate each relationship separately, are worth stating explicitly.
• Nuance: Bilateral involves two parties. Trilateral involves three. Multilateral involves many, aspiring to broad participation. Minilateral groups a few States around a specific issue, sitting between bilateral and multilateral in both flexibility and legitimacy.
• Hindi: द्विपक्षीय (dvipakshīya); बहुपक्षीय is multilateral.
• FAQ: What does bilateral mean? || Involving two parties, most commonly two States acting together or negotiating with each other.
• FAQ: Why might a State prefer bilateral to multilateral engagement? || Bilateral dealings allow tailored bargains, faster decisions and the ability to calibrate each relationship separately, though they carry less collective legitimacy.

Diplomacy

• Pronunciation: /dɪˈploʊ.mə.si/
• Definition: The art and practice of conducting negotiations and managing relations between nations through dialogue, treaties, and agreements.
• Root: Greek diploma = folded document; Latin diploma = letter of authority; French diplomatique → diplomatie
• Origin: From French diplomatie, a back-formation from diplomatique, ultimately from Latin diploma ("a letter of recommendation or authority"), from Greek diploma ("folded document"); first used in English in 1792.
• Part of Speech: noun
• Word Family: diplomat (n), diplomatic (adj), diplomatically (adv), diplomats (n pl), diplomacies (n pl)
• Usage: India's calibrated diplomacy during the Russia-Ukraine conflict, championing strategic autonomy while keeping channels open with all parties, demonstrated how middle powers can convert measured neutrality into genuine geopolitical leverage.
• Synonyms: statecraft, statesmanship, negotiation, tact, discretion, finesse
• Antonyms: belligerence, tactlessness, confrontation, bluntness
• Mnemonic: From Greek diploma, a "folded" document carried by an envoy — a diplomat carries the folded paper and the folded, careful words; diplomacy keeps the sharp edges tucked out of sight.
• UPSC: The conduct of relations between States through negotiation and representation rather than force. The framing that improves a GS2 answer is that diplomacy is an instrument of statecraft alongside economic and military means, not an alternative to them, and its contemporary forms have widened considerably: summit diplomacy, economic diplomacy, diaspora engagement and public diplomacy all pursue the same ends by different routes.
• Nuance: Diplomacy is the conduct of relations through negotiation and representation. Foreign policy is the set of objectives diplomacy serves. Statecraft is the full range of instruments including economic and military. Track II diplomacy is unofficial engagement between non-governmental participants, used where official channels are constrained.
• Hindi: कूटनीति (kūtnīti).
• FAQ: What is diplomacy? || The conduct of relations between States through negotiation, representation and dialogue rather than force.
• FAQ: What is the difference between diplomacy and foreign policy? || Foreign policy sets the objectives a State pursues abroad. Diplomacy is the principal instrument through which those objectives are pursued.

Sovereignty

• Pronunciation: /ˈsɒv.rən.ti/
• Definition: The supreme and independent authority of a state to govern itself without external interference.
• Root: Old French soverainete → Latin super = above; soverain = supreme; -té/-ty = abstract noun suffix
• Origin: From Old French soverainete, from soverain ("supreme"), based on Latin super ("above"); recorded in English from the 14th century.
• Part of Speech: noun
• Word Family: sovereign (n/adj), sovereignly (adv), sovereignize (v, rare), co-sovereignty (n)
• Usage: While the Constitution vests sovereignty in "We, the People," India's federal design distributes its exercise between the Union and the States, demonstrating that sovereignty can be shared in practice even as it remains indivisible in principle.
• Synonyms: supremacy, dominion, autonomy, independence, suzerainty, self-determination
• Antonyms: subjugation, dependence, vassalage, subordination
• Mnemonic: Think "SOVEREIGN" = one who reigns SUPER (above) all — Latin super, "above." The sovereign sits above every other authority, owing allegiance to none.
• UPSC: Supreme authority within a territory and independence from external control. The distinction that carries most GS2 answers is between the internal aspect, supreme authority over everything within the territory, and the external aspect, freedom from subordination to another State. Note also that accepting treaty obligations is an exercise of sovereignty rather than a loss of it, which is the standard reply to arguments that international commitments erode it.
• Nuance: Sovereignty is supreme authority within a territory and independence outside it. Autonomy is self-government within a larger sovereign entity. Territorial integrity concerns the inviolability of borders specifically. Jurisdiction is the legal authority to act in a defined sphere, which may extend beyond a State's own territory in limited cases.
• Hindi: संप्रभुता (samprabhutā).
• FAQ: What is sovereignty? || Supreme authority within a territory together with independence from external control.
• FAQ: Do international treaties reduce sovereignty? || No. Entering treaty obligations is itself an exercise of sovereign choice, and the State retains authority over what commitments it accepts.

Key Terms

India-Nepal Relations

• Definition: India-Nepal Relations denote the multidimensional bilateral partnership between India and Nepal—two Himalayan neighbours sharing an open border, deep civilisational and people-to-people ties, and treaty-based cooperation anchored in the Treaty of Peace and Friendship signed at Kathmandu on 31 July 1950.
• Context: India and Nepal share a roughly 1,750-km open border and a unique relationship marked by free movement of people, shared Hindu-Buddhist heritage, and the recruitment of Nepali Gorkhas into the Indian Army (a practice rooted in the Tripartite Agreement of 9 November 1947). The 1950 Treaty grants reciprocal national treatment in residence, property, trade and movement, but Nepal regards parts of it as "unequal," prompting the creation of an Eminent Persons' Group (EPG) in 2016 to review the relationship. Ties have periodically been strained by the 2015-16 border blockade and the Kalapani-Lipulekh-Limpiyadhura territorial dispute, even as connectivity, energy and trade cooperation have deepened.
• UPSC Relevance: India-Nepal relations is a high-yield GS2 topic under "India and its neighbourhood." Prelims tends to test factual anchors—the 1816 Sugauli Treaty, the 1950 Treaty of Peace and Friendship, the Kali (Mahakali) river dispute, and the location of Kalapani/Lipulekh. Mains demands analytical treatment of the open border, the boundary dispute, hydropower and power-trade cooperation, the China factor, and the stalled EPG report. It is a foundational concept that underpins questions on India's neighbourhood-first policy, cross-border connectivity, and regional water/energy diplomacy.

India-Sri Lanka Relations

• Definition: India-Sri Lanka relations refer to the bilateral ties between the two South Asian maritime neighbours, spanning civilisational, economic, security and developmental cooperation, shaped by shared Buddhist-Hindu heritage, the ethnic Tamil question, fisheries disputes in the Palk Strait, and India's "Neighbourhood First" policy.
• Context: India and Sri Lanka are separated only by the narrow Palk Strait and share deep civilisational links rooted in Buddhism, which travelled from India to the island. The relationship has navigated complex chapters including the Sri Lankan civil war (1983-2009), the controversial IPKF deployment (1987-90), and the Tamil ethnic question. In recent years, India emerged as Sri Lanka's "first responder" during its worst economic crisis in 2022, extending nearly USD 4 billion in assistance, cementing India's role as a trusted development and security partner.
• UPSC Relevance: India-Sri Lanka relations is a high-frequency GS2 theme under "India and its Neighbourhood" and "bilateral, regional and global groupings affecting India's interests." Prelims commonly tests factual anchors such as the Indo-Sri Lanka Free Trade Agreement (in force 2000), the 1974 Katchatheevu maritime boundary agreement, the Palk Strait/Palk Bay geography, and connectivity initiatives like UPI-LankaPay linkage. Mains demands analysis of the fishermen dispute, India's "Neighbourhood First" and SAGAR/MAHASAGAR visions, the China factor (Hambantota port, Colombo Port City), and the Tamil reconciliation question (13th Amendment). This is a foundational concept underpinning questions on India's neighbourhood diplomacy, maritime security in the Indian Ocean Region, and economic statecraft.

Look East Policy

• Pronunciation: /lʊk iːst ˈpɒl.ɪ.si/
• Definition: India's foreign policy initiative launched in 1991 under Prime Minister P.V. Narasimha Rao to cultivate extensive economic and strategic relations with Southeast Asian nations, serving as the foundation for deeper engagement that was later upgraded to the action-oriented Act East Policy in 2014 under Prime Minister Narendra Modi. The policy marked India's strategic pivot towards the Asia-Pacific after decades of focus on South Asia and the non-aligned world.
• Context: Launched in 1991 as a strategic response to the post-Cold War economic landscape, the collapse of the Soviet Union (India's traditional partner and largest trading partner), and the need to integrate with the dynamic economies of Southeast Asia following India's own economic liberalisation. Under the Look East Policy, India became an ASEAN Sectoral Dialogue Partner (1992), joined the ASEAN Regional Forum (1996), gained Summit-level partnership status with ASEAN (2002), and acceded to the Treaty of Amity and Cooperation in Southeast Asia (2003). The policy was further developed under PM Atal Bihari Vajpayee (1998-2004) before being rebranded as the Act East Policy in November 2014.
• UPSC Relevance: GS2 International Relations — Prelims tests the launch year (1991), PM (Narasimha Rao), ASEAN milestones (Sectoral Dialogue Partner 1992, Summit Partner 2002), and upgrade to Act East (2014). Mains 2016 asked candidates to "evaluate the economic and strategic dimensions of India's Look East Policy." The Look East to Act East evolution is a standard framework for IR answer writing — use it to demonstrate India's shift from passive economic engagement to proactive strategic, security, and connectivity-driven diplomacy.

SAARC

• Pronunciation: /sɑːrk/
• Definition: The South Asian Association for Regional Cooperation, an intergovernmental organisation of eight sovereign South Asian nations — India, Pakistan, Bangladesh, Sri Lanka, Nepal, Bhutan, Maldives, and Afghanistan — founded to promote socio-economic development, regional stability, and collective self-reliance. Its member states collectively represent approximately 21% of the world's population and 5.21% (USD 4.47 trillion) of the global economy.
• Context: Established on 8 December 1985 in Dhaka, Bangladesh, through the Dhaka Charter, with seven founding members; the initiative was first proposed by Bangladesh's President Ziaur Rahman in 1980. Afghanistan joined as the eighth member in April 2007. Headquartered in Kathmandu, Nepal, SAARC also has nine observer states (Australia, China, EU, Iran, Japan, Mauritius, Myanmar, South Korea, USA). The organisation has been effectively dormant since the 19th SAARC Summit in Kathmandu (2014); the 2016 Islamabad summit was cancelled after the Uri attack, and no summit has been held since, with India-Pakistan tensions being the primary cause of paralysis.
• UPSC Relevance: GS2 International Relations — Prelims tests founding year (1985), members (8), HQ (Kathmandu), and the distinction between SAARC and BIMSTEC. Mains frequently asks "Compare SAARC and BIMSTEC as regional cooperation platforms" and "Why has SAARC become dormant?" Always note: (1) India-Pakistan tensions as the structural cause of SAARC's paralysis, (2) India's shift to BIMSTEC (excludes Pakistan) and sub-regional groupings like BBIN as functional alternatives, and (3) China's observer status and its growing influence in the region as a complicating factor.
