Since Canada made the first anti-dumping code in 1904,United States,Australia and France made their domestic anti-dumping codes successively.In 1947, the contracting parties made anti-dumping rules part of GATT (Article VI).Due to the broad use of tariff and non- tariff trade barriers,few countries turned to anti-dumping measures in 1950s.Recently,because of the reduction of tariff and the restrictions on non-tariff barriers,the number of anti- dumping cases increases very quickly.For example,the total anti-dumping initiations in 1980 are 69,while the number of anti-dumping initiations in 2001 is 366.
