The Chinese leadership will continue to do the cool headed and patient thing rather than the hot headed and impulsive thing, just like they have been doing for two generations at this point. How many times do expectations of hardball foreign policy need to be subverted for you to understand this.
Plus the pool of intelligent and educated per citizen is in China's favor, it's estimated the Chinese have more intelligent citizens than that of America by a large margin. Not to mention a more energized, active, dedicated and drug free/addict free populous compared to its western counter part, the ball is simply to put it in China's park. China already has a stronger economy than America's and has substantially more buying power, they cannot compete with the next level of civilization China is on.
