Analysis of the Trilateral Cooperation Path of China, Japan and South Korea under the RCEP Framework

RCEP will reconstruct the regional industrial chain from various aspects, and further industrial cooperation between China, Japan and South Korea will also face many opportunities and challenges. This paper draws on the theory of international cooperation and puts forward a research framework of "power-institution-collective identity" on the basis of realist power cooperation theory, liberal institutional cooperation theory and constructivist identity cooperation theory. And through research, a new path for cooperation is proposed: ①Interest-oriented: Increasing the degree of trilateral interdependence. ② Institutional Guarantee: Promote the Institutionalization of Cooperation. ③ Conflict Resolution: Building Regional Collective Identity.
