Not necessarily. But China's aggression towards Taiwan and their recent rare earth metals move last year show that China does not have the worlds best interests at heart either. We're picking between two evils and China's evil is more predictable than the US's right now.

This goes for Asia in general. Korea, Japan, and China spent centuries fighting and making them the de facto super power makes it easy to resume the Korean war or try to overtake the (military wise) crippled Japan should they be emboldened by the faltering/collapse of NATO.
