Unrelated note, but China is actually pretty strict and they would be capable to make the World Cup work out, but if nothing changes in the near future, it will be completely impossible for the athletes themselves.
Right now, there's an eSports World Championship being held in Shanghai, with European, North American, Korean, Southeast Asian, Russian, South American, Japanese, Australian and Turkish teams that have travelled there.
All of them were individually locked up in a hotel room that they couldn't leave for 14 days and would only open their door to pick up their food delivery.
In the further stages of the tournament it's also mentioned that a smaller, spread out audience will be able to attend the stadium live.
I've been following the journey of the pros closely on Twitter, Instagram, Twitch and other media, so this is one of those rare times when I can say that China is really doing their best to make such a huge event happen.
Since they are e-athletes, they could've practiced from the room and that's why I wouldn't put my money on a World Cup happening there, because it would screw up all of the athletes to be in lockdown for 14 days and I'm not too optimistic that their strict regime towards travelling is going to severy change in the following 3-4 months.
