China holds all the cards
Not all the cards. China is - in some ways - like the uncontrolled and empowering Germany of the early XXth. They're the young new world superpower which doesn't have a superpower-history long enough to feel how dangerous it can be to lack diplomacy and look for trouble every other week. That obnoxious behavior is particularly strong and obvious since a couple of years ago - which is worrying. China is powerful thanks to its economic and commercial ties with most of the rest of the world. Unless there is an international comercial/economic consensus to return China to reason, China will keep growing until it is out of reach.
