Summary
Most Favored Nation (MFN) status is a foundational principle in international economic relations, ensuring that a country granting this status extends the same trade advantages, such as low tariffs or high import quotas, to all other countries with MFN status. This non-discriminatory approach is a cornerstone of World Trade Organization (WTO) trade law, alongside national treatment, and is enshrined as the first article of the General Agreement on Tariffs and Trade (GATT). While historically MFN treaties could create exclusive clubs, under the WTO, it mandates equal treatment among all member nations, promoting stable and predictable global trade. The concept has also been explored domestically, such as the Trump administration's executive order aiming to leverage MFN status to lower drug prices in the United States, though this raised concerns about potential impacts on pharmaceutical research and development and the role of middlemen.

In international economic relations and international politics, most favoured nation (MFN) is a status or level of treatment accorded by one state to another in international trade. The term means the country which is the recipient of this treatment must nominally receive equal trade advantages as the "most favoured nation" by the country granting such treatment (trade advantages include low tariffs or high import quotas). In effect, a country that has been accorded MFN status may not be treated less advantageously than any other country with MFN status by the promising country. There is a debate in legal circles whether MFN clauses in bilateral investment treaties include only substantive rules or also procedural protections. The members of the World Trade Organization (WTO) agree to accord MFN status to each other. Exceptions allow for preferential treatment of developing countries, regional free trade areas and customs unions. Together with the principle of national treatment, MFN is one of the cornerstones of WTO trade law. "Most favoured nation" relationships extend reciprocal bilateral relationships following both the General Agreement on Tariffs and Trade (GATT) and WTO norms of reciprocity and non-discrimination. In bilateral reciprocal relationships a particular privilege granted by one party only extends to other parties who reciprocate that privilege, while in a multilateral reciprocal relationship the same privilege would be extended to the group that negotiated a particular privilege. The non-discriminatory component of GATT/WTO applies a reciprocally negotiated privilege to all members of GATT/WTO without respect to their status in negotiating the privilege. Most favoured nation status is given to an international trade partner to ensure non-discriminatory trade between all partner countries of the WTO. A country which provides MFN status to another country has to provide concessions, privileges, and immunity in trade agreements. It is the first clause in the GATT. Under rules of WTO, a member country is not allowed to discriminate between trade partners and if a special status is granted to one trade partner, the country is required to extend it to all members of WTO. In a nutshell, MFN is a non-discriminatory trade policy as it ensures equal trading among all WTO member nations rather than exclusive trading privileges.

- Most Favored Nation (MFN) In International Trade Explained
The most favored nation (MFN) principle is an important rule in global trade. It acts as a non-discriminatory trade policy, meaning a country must give the same trade terms to all its partners. If one country receives a benefit, like a lower tariff, then all trading partners should get the same. This rule helps prevent favoritism and makes trade more stable and predictable. [...] In different contexts, MFN might be called “most favored customer” or “best-in-class pricing.” These terms reflect the same idea: fair and equal treatment for everyone involved. MFN applies across goods, services, and tariffs. For goods, it ensures that all countries get equal tariff rates, which benefits exporters. For services, it gives foreign providers the same opportunities as local ones. When it comes to tariffs, MFN requires equal rates on imports from all partners, which helps reduce [...] This means that whenever Country A gives a trade benefit to one partner, it must extend that benefit to all partners with MFN status. So, if Country A offers a reduced steel tariff to Country B, Country C automatically receives the same lower rate. This rule keeps trade fair and prevents favouritism, building stable and equal trade relationships between countries. ## Historical Background of the MFN

1. Most-favoured-nation (MFN): treating other people equallyUnder the WTO agreements, countries cannot normally discriminate between their trading partners. Grant someone a special favour (such as a lower customs duty rate for one of their products) and you have to do the same for all other WTO members. [...] This principle is known as most-favoured-nation (MFN) treatment (_see box_). It is so important that it is the first article of the General Agreement on Tariffs and Trade (GATT), which governs trade in goods. MFN is also a priority in the General Agreement on Trade in Services (GATS) (Article 2) and the Agreement on Trade-Related Aspects of Intellectual Property Rights (TRIPS) (Article 4), although in each agreement the principle is handled slightly differently. Together, those three agreements [...] Most-favoured nation (MFN) status did not always mean equal treatment. The first bilateral MFN treaties set up exclusive clubs among a country’s “most-favoured” trading partners. Under GATT and now the WTO, the MFN club is no longer exclusive. The MFN principle ensures that each country treats its over—140 fellow-members equally. But there are some exceptions ... Image 10: show previous pageImage 11: show next page #### About WTO
