Corrupt Chinese politicians are moving a lot of money from China to western countries.
It's not a good phenomenon for becoming Super Power.
Why not. Lots of Chinese money gos into Africa. Africa have lots of minerals that China dont have. Now with USA getting enough oil they need and will slowly release their clutches of Middle East, China will move there also. No matter how good relations they have with Russia, China will want their own Oil sources for their keep on expanding industry.
Biggest challenge China will have in near future is Ecology. I am not afraid they will not be able to successfully win the fight with this problem, but the fight will be long and hard.
