Since the Chinese discovered America first, they now have a historical claim. America is no a renegade province that must accept rule from Beijin. To impose it's will, China will make long terms plans to hold American capital and displace local American manufacturing in otrder to make America dependent on the Chinese for imports America no longer produces. Wait, that's already happened.
Where did the Chinese come from? Weren't the Mongols there first? maybe the Chinese are actualy decendants of the Japanese, or a blend of Mongols and Japanese.
