P.L. 100-418 (August 23, 1988) provided the President with negotiating authority for the General Agreement on Tariffs and Trade (GATT) Uruguay Round, U.S.-Canada Free Trade Agreement, and the North American Free Trade Agreement, and specified U.S. negotiating objectives regarding agriculture. The law revised statutory procedures for dealing with unfair trade practises and import damage to U.S. industries. It gave USDA discretionary authority to trigger marketing loans for wheat, feed grains, and soybeans, if it is determined that unfair trade practises exist.
