Unfortunately, they will get away with it; they already have. Chen walked back out (supposedly of his own accord). The 'authorities' will bide their time, and when the world has lost interest, they will fuck him over bigstyle; not because he's actually causing any actual slowdown in their rape of the Middle Kingdom, but simply because they can.
The US has already lost. They had one chance to do their Captain America thing for truth, justice, and whatnot, and they didn't. They are now officially #2, and China is Jabba the Hutt.
The depressing thing is, when China eventually disappears with a big sucking sound up its own rectum and takes half the planet with them, the scumbags who arrange this kind of stuff will be just fine.
