Seven rounds of negotiations occurred under the General Agreement on Tariffs and Trade (1949 to 1979). The first real GATT trade rounds (1947 to 1960) concentrated on further reducing tariffs. Then the Kennedy Round in the mid-sixties brought about a GATT anti-dumping agreement and a section on development. The Tokyo Round during the seventies represented the first major attempt to tackle trade barriers that do not take the form of tariffs, and to improve the system, adopting a series of agreements on non-tariff barriers, which in some cases interpreted existing GATT rules, and in others broke entirely new ground. Because not all GATT members accepted these plurilateral agreements, they were often informally called "codes". (The Uruguay Round amended several of these codes and turned them into multilateral commitments accepted by all WTO members. Only four remained plurilateral (those on government procurement, bovine meat, civil aircraft, and dairy products), but in 1997 WTO members agreed to terminate the bovine meat and dairy agreements, leaving only two."The GATT Years: from Havana to Marrakesh". .

Despite attempts in the mid-1950s and 1960s to establish some form of institutional mechanism for international trade, the GATT continued to operate for almost half a century as a semi-institutionalized multilateral treaty régime on a provisional basis.Footer, M.
