when USA starts to panic about China's speed and potential rise, and wants to prevent China in every possible way, this fact alone means China is indeed not a small potato any more. Of course, whether USA wants to "struggle" against China and still win, that's really a billion dollar question. The worst scenario is USA and China both lose in some way, and other powers (like Europe) will arise and beat USA in economy and technology. Of course, this will be a long journey in a time window of several decades. China is not Japan, its market and potential power can hurt USA hard if it determines to do so because a dictator-style government can work more efficiently in a war without considering consequence and sacrifice.
很明显是打脸川川,一点儿客气都不讲
