I think I disagree that this is Whataboutism. I did not get the impression that the commenter was trying to "discredit an opponent's position by charging them with hypocrisy" (from the wiki link), but rather that he/she was pointing out an instance of apparent double standards.

I could be wrong. He/she might be attempting to defend China's policies. It just didn't come across that way to me.
