What is Most Favoured Nation (MFN)?

Most Favoured Nation (MFN) is a foundational principle of the World Trade Organization enshrined in Article I of the General Agreement on Tariffs and Trade (GATT), 1994. Under this principle, if a WTO member grants a trade advantage — such as a lower customs duty — to one trading partner, it must extend the same advantage to all other WTO members immediately and unconditionally.

Despite its name, MFN does not mean "special treatment" — it means equal, non-discriminatory treatment. Along with the National Treatment principle (Article III, GATT), MFN forms one of the two cornerstones of WTO trade law. The principle ensures a level playing field and prevents arbitrary trade discrimination.

However, there are permitted exceptions: Regional Trade Agreements (RTAs) and Free Trade Agreements (FTAs) under GATT Article XXIV, the Generalised System of Preferences (GSP) for developing countries under the Enabling Clause, and security exceptions under GATT Article XXI.

Current Status / Latest Developments

  • India revoked MFN status to Pakistan on 16 February 2019 following the Pulwama terror attack (14 February 2019, 40 CRPF personnel killed). India simultaneously raised customs duty on all Pakistani goods to 200%.
  • Pakistan had never reciprocated India's MFN status (granted in 1996), maintaining a "Positive List" approach allowing only limited Indian goods.
  • As of 2025, the 200% customs duty remains in force. Bilateral trade collapsed from USD 2.41 billion (2018) to just USD 1.2 billion (2024); Pakistani exports to India fell from USD 547 million (2019) to a mere USD 480,000 (2024).
  • The WTO does not have a specific enforcement mechanism for MFN withdrawal on political/security grounds — India invokes the Article XXI security exception.
  • Globally, the MFN principle faces challenges from the rise of bilateral/plurilateral deals, US-China tariff wars, and WTO dispute settlement crisis.
