Hard to say. They will claim this is only Flag of convenience as they are caught. However China still has the opportunity to say that this is something for their law enforcement to take care of not international, and then give the captain "a slap on the wrist".

What we don't know is if China knew they were going to try this beforehand or not. Flag of Convenience is common enough that we can't be sure. This could have been planned on the high level from China and we would never know - something conspiracy theorists will run with! If China knew they would probably give the crew a sever punishment, but unofficially it is for getting caught and not doing the act. Most likely though China didn't know before hand.
