The primary focus of this article is to address the necessity and importance of cooperation among the two Koreas and China who are unfamiliar with close consultations on their common interests. The Northeast Asian region, whose politico-economic order in transition, consists of all ‘handicapped’ actors whose internal and external relations are defined-directly and indirectly-by the expanded capabilities and interests of the United States, that is, the global superpower. What is currently causing the transformation of the traditional architecture in Northeast Asia is the desire by each of those ‘handicapped’ states to turn itself to a ‘normal state.’Among many, the Republic of Korea(ROK), the Democratic People’s Republic of Korea(DPRK) and the People’s Republic of China(PRC), that are all geographically linked, are increasingly requested to develop their communication skills in dealing with conventional and non-conventional issues for their common interests such as economic development and regional stability. Especially, Korean reunification may serve as a critical breakthrough for the facilitation of multilateral cooperation among not only the trio but also many other concerned parties.
