Japan–China rivalry: What role does the East Asia Summit play?

Although economically interdependent, political rivalry between Japan and China have brought about the inability of the Association of Southeast Asian Nations Plus Three (APT) process to transform itself into an East Asia Summit (EAS) as originally envisioned. The existence of the APT and the EAS as two separate entities not only reflected the politico‐security rivalry between the two neighbours but more importantly affected the direction and progress of East Asian regionalism as a whole. Aiming to provide a historical account of the EAS process and examine Japan's role in the development of the EAS framework, this paper argues that Japan has put greater attention on the EAS and made numerous unilateral initiatives to develop it. While Japan does not seek ultimate power, it considers the EAS as an excellent opportunity to: (i) raise its influence in the region vis‐à‐vis China; (ii) elevate the status of the EAS in region‐building and (iii) check Chinese advances by fulfilling its long‐held policy of having other Asia Pacific countries, primarily Australia and New Zealand, join. Nevertheless, the decision to expand the EAS to include the USA and Russia will have some adverse effects on Japan's unilateral ambitions and the furtherance of regionalisation processes.
