Hard to say.
China's arrested/kidnapped (depending upon whose version you choose to believe) the head of Interpol, for crimes he supposedly committed, and then "allegedly" forced him to announce his resignation from that position, afterwards. I don't recall seeing those specified back at the time this occurred.
Presumably, that "resignation" would have been done to keep the Chinese from dealing harshly with his wife, and the rest of his family as well, if he chose not to accede to their wishes.

Not sure if they were cracking down on his corruption, or cracking down on him because he knew of and was dealing with Chinese corruption, and/or those attached to that.
I also find it very interesting that the Interpol organization doesn't seem to be doing anything to investigate the disappearance of it leader, either.
Of course, like Iran, North Korea, and Russia, China is now also kidnapping foreigners and holding them as bargaining chips against countries that are cracking down on their citizens crimes, or in protest over various sanctions levied on them by various countries too.
Seems like the heady days of the medieval and renaissance era are back again, and what's old is new.
