I do expect china to do these things and I will be sursprised if they don't. Now having said that do I dislike the idea of China becoming a superpower? ABSOLUTELY Why? Not because I don't want there to be a balance of power but because I don't want China to have that power. Admititly the US is not perfect but would China be a responsible major power?
China is a dictatorship that :
represses reproductive rights
religious freedoms
political experession
arms unstable regimes with dangerous weapons
restricts freedom of information to it's citizens
monitors it's citizens
What good would come of China with it's current policies becoming a superpower?
