Stability in Northeast Asia has been challenged in recent years by a newly developing imbalance of power between North and South Korea. The American, Japanese, and South Korean policy communities, respectively, have been divided on how to coordinate policy in the event of either sudden or gradual change in North Korea. Although formal policy coordination efforts have been initiated among governments through the proposal for Four Party Peace Talks and the Geneva Agreed Framework, divisions continue to lie under the surface, reflecting differing priorities. Through interviews with policy makers, political leaders, and specialists in Japan, South Korea, North Korea, and the People's Republic of China, the author will investigate sources of policy divisions, explore mechanisms for strengthening regional policy coordination toward the Korean Peninsula, consider predicted and preferred settlements of the Korea question among Northeast Asian countries, and examine implications for the post-Cold War security environment in Northeast Asia.
