EVERY CCP apparatchik is corrupt. The only ones who get investigated/charged with corruption are political enemies of Xi Jinping.
And often people who won’t go along with either any, or enough, corruption and other criminal activity.
Tellingly, the MSM here will often report that Xi and the CCP are cracking down on corruption, without a hint of questioning the story, while if Trump or Republicans criticize corruption, they will put it in scare quote, as in “corruption.”
