The Sino-U.S. relationship, among all the key Asia-Pacific bilateral match-ups, has experienced the greatest swings in recent years, from the highs after the Clinton-Jiang summits to the lowest low immediately after the accidental bombing of the Chinese Embassy in Belgrade, with many upward and (mostly) downward cycles in between. It is also the bilateral relationship which, if not properly managed, could most likely plunge the region into a new cold, and perhaps even actual, war.
