This course provides an introduction to international trade law. We begin by examining justifications for liberalizing international trade, as well as arguments for limiting such liberalization. We next discuss the institutional dimension of the international trade regime (WTO), as well as the way in which international trade rules are negotiated and implemented in the United States and the EU. We then move onto core trade principles, such as most-favored nation and national treatment in goods and services trade, as well as the non-economic exceptions to international trade obligations. Based on this knowledge of substantive international trade law, we discuss the WTO dispute settlement system, including its relationship to regional free trade institutions such as the EU and NAFTA, and the relationship between WTO law and other parts of the international legal system (for example, environmental and human rights law).
