What makes you ask a such question? Here are some bad ideas which comes to my mind:
* you think China is inferior?
* or maybe Chinese are inferior?
* maybe you think they always lie?
* or maybe they don't have laws?
* maybe plain old racism?
Forgive me, but your question sounds so bad. Counter question, did any of war criminals get a fair trial in the USA? (I am not listing countries they did war crimes, because there are too many)
