China needs to double down on support for it. Encourage them. Give them major media coverage for it. Show other streamers that making China look good gets you in front of a billion people on national tv. Seeing this will cause more and more to do it.

If there is money involved, they will all become huge supporters.

You can get all the gamers with this strategy too. Get the biggest most popular commentators doing commentary for hype tournaments based in China, get them saying good things about China, get the players saying good things about China by making them see China as the future of esports or whatever the fuck. If it's where the biggest money is, it'll get their support.

The propaganda will break down.
