China: An emerging super power?

I keep hearing that China is going to become so very powerful and soon.

I honestly don't think China will be a super power soon, they have too many internal problems (rift between rich and poor, corruption, enviornment, various social issues, etc...)

Is it just people talking about things they don't really know anything about or is there some truth to this?  Thoughts?

China has been working for Yankee-Dollars during the last 20 years. They hold the biggest single amount of dollars ever seen. If they happen to go shopping with their dollars, they could buy the complete USA industry twice, except the Military-Industrial-Complex of course. The dollar wouldn't even be worth the paper it's printed on then. That's why we hear voices calling for a new world currency lately.
