This course examines the major treaties affecting what states can do to protect their own economies from foreign competition. The principles of the General Agreement on Tariffs and Trade (GATT) are discussed as well as the provisions for the Canada-U.S. Free Trade Agreement (FTA) and the North American Free Trade Agreement (NAFTA). Examples of trade conflicts between Canada and the U.S. (softwood lumber, steel) are discussed to show the application of these agreements to actual trade disputes. The laws affecting investment disputes between states will be examined and the relationship of trade law rules to environmental concerns are also addressed. Completion of a course in international law is preferred, but not required.
