What is Most-Favoured-Nation (MFN) Policy?
Historical Background
Key Points
10 points- 1.
Any trade advantage, privilege, or immunity granted by one member country to a product originating in or destined for another country shall be accorded immediately and unconditionally to the like product originating in or destined for all other member countries. This means if India offers a lower import duty on apples from Chile, it must offer the same lower duty to apples from the USA, Argentina, and all other WTO members.
- 2.
The MFN principle ensures that all WTO members are treated equally. This prevents a situation where a country might give a very low tariff to its closest ally and a very high tariff to a rival, thus distorting trade patterns and creating unfair competition.
- 3.
MFN exists to prevent protectionism and discrimination in international trade. Without it, countries could easily favour their own industries or specific partners, leading to a fragmented global market and hindering overall economic growth. It promotes a 'level playing field'.

Recent Developments
5 developmentsIn 2026, drugmakers began delaying new medicine launches in Europe, citing concerns over potential US drug pricing reforms, specifically the 'Most-Favoured-Nation' (MFN) policy. This policy aims to link US drug prices to lower rates in other developed countries.
The US administration's push for MFN-style pricing in pharmaceuticals has created significant uncertainty for European markets, leading companies to reassess their launch strategies for new drugs.
Companies are concerned that if they launch drugs at lower prices in Europe to comply with potential MFN-like pressures, these lower prices could be used as benchmarks to force down prices in the much larger and more lucrative US market.
This strategic pause in European drug introductions highlights the global interconnectedness of pharmaceutical pricing and the significant influence of US policy on international market dynamics.
The situation underscores a broader debate about drug affordability, innovation incentives, and the extraterritorial application of national pricing policies, with potential implications for patient access to new medicines worldwide.

Frequently Asked Questions
121. In an MCQ about Most-Favoured-Nation (MFN) Policy, what is the most common trap examiners set regarding its scope?
The most common trap is assuming MFN applies to *all* trade advantages or agreements. In reality, MFN, as enshrined in WTO's Article I, primarily applies to tariffs, quotas, and other trade barriers on 'like products'. It does *not* automatically extend to preferential treatment granted within Free Trade Areas (FTAs) or Customs Unions, which are permitted exceptions under WTO rules. MCQs often present a scenario where a country offers a special deal within an FTA and asks if MFN mandates extending it to all WTO members, which is incorrect.
Exam Tip
Remember: MFN is the *general* rule for non-discrimination, but FTAs/Customs Unions are *specific exceptions* where deeper integration is allowed among a subset of countries.
2. What is the one-line distinction between Most-Favoured-Nation (MFN) Policy and National Treatment?
MFN ensures equal treatment *between* trading partners (if you treat one partner well, you must treat all others equally), while National Treatment ensures equal treatment *within* a country for imported goods compared to domestic goods once they have entered the market.
