The spectre of international trade changed dramatically on 1 January 1995 as nations accounting for over 90 per cent of world trade, simultaneously embraced the World Trade Organization on 15 April 1994. The Most Favoured Nation (MFN) principle has been the strongest pillar upon which the WTO foundations for global free trade have been laid. In other words, under the WTO, each of its members treats all othermembers equally as âmost favouredâ trading partners. However, some exceptions to the MFN philosophy are permitted by the WTO; the most noteworthy exception being, setting up of an economic bloc between members of a region or between any number of WTO members. While on one hand, the WTO is finding it difficult to bring all member nations to the negotiating table to take the Doha Agenda forward, the rapid proliferation of Regional Trading Arrangement has raised a question mark on the political will of member nations to even support WTOâs Multilateral Trading regime.
