The 2018 games are in S. Korea, which could be problematic since China has banned all kpop, and Korean entertainment in general in response to S. Korea's missile defense upgrades [1].

It would be very difficult to cover the games without any singing or tv drama stars being on screen at some point. Not sure if the Olympics themselves would fall under "Korean entertainment" or not.

At the 2008 Beijing summer olympics they actually reduced the censorship a little until the games were over.
