China is matching America's manufacturing and will likely double it in 20 years. If you think America had too much power, you haven't seen nothing yet. China will OWN the world by 2100.
What should make you very nervous is that China actively loathes Japan. This is the one of reasons that I have a problem about obsessing over sins of the past. This constant picking at things someone's ancestors did FOSTERS and ENCOURAGES hatred and could lead to mass death, war and chaos in the present.
When China dwarfs America in both economic and military might, what do you think is going to happen to Japan? Could there a bit of a conflict there? Could China attempt to get a little payback for the butchery of WWII?
In the meantime I suspect China and India could come into conflict. That would end very poorly for India. I don't think China will go into colonization mode but I definitely believe it is going to go ahead and take bits and pieces that are in its strategic best interest to have.
