It is tempting to see the hardening of U.S.-China relations as a temporary phenomenon, a product of unique features of contemporary international politics, the Donald Trump presidency in the United States in particular. Resist that temptation.

The U.S. consensus about the nature of its relationship with China has shifted to the right; it is difficult to find anyone who dissents from the view that the two countries are locked in an intense competition that threatens to spiral into a new Cold War.

This in turn validates the Chinese belief that the U.S. is determined to thwart its rise and encourages a nationalism and readiness to sacrifice on behalf of the nation that harkens back to the Long March. Together, these two perspectives virtually ensure that the U.S.-China relationship will become more confrontational. Japan must prepare for the impact.
