The end of the Cold War, the rise of China, globalisation, free trade agreements, the war on terror, and an institutional approach to keeping the peace are causing dramatic shifts in relationships among countries in East Asia. A new regional architecture in the form of trade, financial, and political arrangements among countries of East Asia is developing that has significant implications for U.S interests and policy. This book examines this regional architecture with a focus on China, South Korea, Japan, and Southeast Asia.
