The General Agreement on Tariffs and Trade (GATT) is a trade treaty that has been in operation since 1948, to which 95 nations are party and a further 28 nations apply its rules de facto; thus some 90% of world trade is governed by GATT regulations. Its objectives are to expand world trade and to provide a permanent forum for international trade problems. Special attention is given to the trade problems of developing countries. The Tokyo round, concluded in 1979, agreed many tariff reductions, non-tariff measures, and a revised anti-dumping code. The Uruguay round, begun in 1986, is conducting negotiations on non-tariff measures, subsidies, safeguards, etc. The GATT office is in Geneva. Research GATT
