The aim of this course is to introduce and analyse the international relations of Northeast Asia. With four great powers – China, Japan, Russia and the extraterritorial United States, four nuclear weapons states, three of the world’s largest economies and the largest concentration of divided polities, Northeast Asia is one of the most dynamic yet volatile regions in world politics. During the Cold War, Northeast Asia was the site of intense competition and conflict between the superpowers and among the states in the region. In the post-Cold War era, the region has been an engine of the global economy while undergoing a major shift in the balance of power whose trajectory and outcome remain uncertain. The first part of the course will provide a historical and theoretical overview of Northeast Asia’s international relations. The second assesses competing explanations for the international behaviour and interactions of the region’s major powers. The final section examines four multilateral/transnational issues as sources of potential conflict and cooperation.
