I think the issue is specifically because the Chinese ai is open source.
The western private ai can not compete with open source ai, there is no business model where they can win.
The only option they have is to get it regulated out of the market and the only way to do that is to kick up fear that ai is dangerous and needs to be given strict safety measures to prevent it from breaking containment and going wild.
There's no way to contain open source, so open source ai will have to be restricted.
This was like a lightbulb "Ohhhhhhhhhhhhhh" moment for me when I realised it was about private closed source vs open source. You can restrict "safety" for the private one but you can't make what random people do with open source safe so you just have to shut it down. That's where they're planning to go with this.
