The Korean War, an ideological war that created North and South Korea as we know it today, was predominantly caused by the bipolar powers at that point in time. The US supported the democratic South Korea while the USSR established a communist regime in the North. This eventually led to a full-scale conflict when North Korea invaded the South in an attempt to reunite the nation. China, on the other hand, has its foreign policy almost designed especially for the US. The 1999 bombing of the China embassy in Belgrade and the 2001 plane collision incident sparked mass protests in China and prompted the China government to denounce the US openly. US and China relations have always been testy and both countries actually see their relationship as a zero-sum game, where one party gains when the other loses. Thus, it is evident that East Asia today as we know it is indeed heavily influenced by world powers.
