The whole situation has been a disaster. China's sovereignty has been grossly violated by the USG who continue to act as the worlds supreme arbiter of justice under the laughable guise of "human rights". The correct action would have been to simply ignore Chen's pleas and let China deal with him internally. But oh no, big bad Hilary Clinton and her gang just HAD to intervene and rescue the guy. The Chinese state did the requisite whining of displeasure, but in the end bowed down to the demands of the USG.
If China really wants to compete with the US in the global political environment, it has to learn when to say NO. Otherwise, it'll be non-stop kowtowing until who knows when. Talk about losing face.
