Why no one mentioned the big difference between china and japan? Japan is actually a dependant state of usa. So usa can take advantage of japan whenever it wants, consider the Plaza Accord when usa destroyed japan's economy. China, whatever you name it, is a independent nation. It is not easy to order China to do something, not like japan.
