This book assesses the importance of enhanced ASEAN-Japan cooperation as a step toward a greater East Asian regional community. Fifteen international relations experts from ASEAN (Association of Southeast Asian Nations) countries and Japan, as well as China, South Korea, and the United States, review the history and current status of this bilateral relationship and propose how it can be strengthened. Chapters review the history of ASEAN-Japan relations and the rationale for renewed emphasis on cooperation; assess ASEAN as a regional unit and Japan as a regional actor; consider the implications for the relationship of changing regional and international environments; examine the future direction of economic, political, and security relations between the two actors; and evaluate societal and cultural areas of cooperation.
