For almost half a century (until 1994), the GATT's basic legal principles remained much as they were in 1948, and several other meetings were held on further decreasing tariffs, among other relevant issues. For example, the Kennedy Round in the mid-sixties brought about a GATT Anti-Dumping[2] Agreement. The Tokyo Round during the seventies was the first major attempt to tackle trade barriers that do not take the form of tariffs and to improve the system.
