What is India-Sri Lanka Relations?
India-Sri Lanka relations describe the multifaceted partnership between India and its southern island neighbour, separated by the Palk Strait. The ties rest on shared Buddhist-Hindu civilisational heritage, ethnic and linguistic links (the Sri Lankan Tamil and Indian-origin Tamil communities), and a dense web of trade, development assistance and maritime-security cooperation. Sri Lanka is central to India's "Neighbourhood First" policy and its Indian Ocean vision.
Key Pillars of the Relationship
Trade and economy. India is Sri Lanka's largest trading partner. Bilateral merchandise trade stood at about USD 5.8 billion in FY 2024-25 (India's exports ~USD 4.5 billion). The Indo-Sri Lanka Free Trade Agreement (ISFTA), signed in 1998 and in force from 1 March 2000, was Sri Lanka's first bilateral FTA; negotiations on a wider Economic and Technology Cooperation Agreement (ETCA) covering services have been revived. India is also among the largest sources of FDI into Sri Lanka.
Development partnership. Since 2005, India has committed over USD 6 billion in credit (Lines of Credit) and around USD 780 million in grant assistance (as of early 2025), making Sri Lanka a flagship of Indian development diplomacy. Projects span housing, railways, Kankesanthurai harbour and the Jaffna Cultural Centre.
Crisis response. During Sri Lanka's 2022 sovereign-default crisis, India extended nearly USD 4 billion (2022-23) via credit lines, currency swaps and deferred payments, and was the first creditor to give financing assurances enabling the IMF's USD 3 billion Extended Fund Facility (approved March 2023).
Sensitive Issues
| Issue | Crux |
|---|---|
| Fishermen & Palk Bay | Frequent arrests of Tamil Nadu fishermen for crossing the IMBL; bottom-trawling depletes Sri Lankan waters |
| Katchatheevu | Uninhabited islet ceded to Sri Lanka under the 1974 maritime agreement; politically contentious in Tamil Nadu |
| Tamil reconciliation | Demand for full implementation of the 13th Amendment and provincial devolution |
| China factor | Hambantota port (99-year lease, 2017) and Colombo Port City raise strategic concerns |
Current Status (2024-2025)
UPI-based digital payments went live via the NPCI-LankaPay linkage (rolled out February 2024), boosting tourism and fintech connectivity. PM Modi's April 2025 visit—the first by a foreign leader after President Anura Kumara Dissanayake took office (September 2024)—saw seven MoUs exchanged covering defence, energy, connectivity and digitisation, plus debt-restructuring amendatory agreements and joint inauguration of five India-assisted projects. Energy cooperation (Trincomalee hub, grid interconnection, Sampur solar project) is advancing.
UPSC Angle
Aspirants should master the geography (Palk Strait, Palk Bay, Gulf of Mannar, Katchatheevu), the chronology (ISFTA 2000, IPKF 1987-90, civil war ending 2009), and the strategic frame: how India balances economic generosity, the Tamil question, and the China challenge in the Indian Ocean Region. Link the topic to "Neighbourhood First," SAGAR, and India's role as a net security provider. This is a recurring GS2 area where current developments must be paired with structural understanding.
