USTR's Office of Agricultural Affairs is the U.S. Government lead for agricultural trade negotiations and the development and coordination of U.S. agricultural trade policy.  Staff work with the USTR’s Chief Agricultural Negotiator to remove trade barriers for U.S. agricultural exports, and collaborate with colleagues across the U.S. Government, particularly the U.S. Department of Agriculture (USDA)to advance U.S. trade interests.
