India rallied 51 countries at the World Trade Organization (WTO) to reject a US presidential memorandum, which had sought to deny special and differential treatment (S&DT) to developing countries in current and future trade agreements. There are no WTO definitions of “developed” and “developing” countries. Members announce for themselves whether they are “developed” or “developing” countries. However, other members can challenge the decision of a member to make use of provisions available to developing countries. The WTO Agreements contain provisions which give developing countries special rights. These are called “special and differential treatment” provisions. About two thirds of the WTO’s around 150 members are developing countries. They play an increasingly important and active role in the WTO because of their numbers, because they are becoming more important in the global economy, and because they increasingly look to trade as a vital tool in their development efforts. Developing countries are a highly diverse group often with very different views and concerns. The WTO recognizes as least-developed countries (LDCs) those countries which have been designated as such by the United Nations. There are currently 47 least-developed countries on the UN list, 36 of which to date have become WTO members.
