The main questions in the paper are what strategy the U.S. employ can effectively balance against China's revisionism and assertiveness in Asia, how the theory of balance of power applies to the rise of China and the countermeasure of the U.S., and how Taiwan's security is in line with American national interests in Asia. This paper argues that the U.S. balancing against China correspond with the theory of balance of power, how the deterrence policy works better for the U.S. against China' expansionism and strengthening Taiwan's security is significantly consistent with American interests which the spirit of Taiwan Relations Act embodies.
