The authors analysis of Chinas relations with the countries of East Asia in the post-Cold-War era is seen from the perspectives of neorealism in general and by the utilization of the concepts of balance of power and the notion of strategic culture in particular. It is boldly argued that Chinas behaviour towards other nations in East Asia is a source of great anxiety and tension. China with its military build-up, its provocations, foreign and defence policies and others serve as a major security threat. In the final analysis, the author calls for the United States to play a more assertive role in the region to counter-balance Chinas potential expansionist goals.
