There's no need for a ban. There's already no use at all of Chinese models in the US simply because they're Chinese.
As of writing, https://openrouter.ai/rankings shows only Opus, Sonnet, and GPT 5.5 in the top twenty by usage (Opus and Sonnet both have two slots on the 4.7/4.8 and 4.5/5 splits respectively, read that how you will).
I don't know how much business OpenRouter does in Europe (they have some GDPR text in some settings pages I think) but it's zero in China.
You might also consider the countless companies that do nothing but open weight LLM inference: Together (of Tri Dao fame), Fireworks (founded by my old colleague), Baseten, SambaNova (of Chis Re fame), and too many more to count, there's a new one every week. Plus NVIDIA does a ton of this business via NIM and shit.
I'm trying to be reasonably polite because it's possible you literally didn't know that, but this reads as a troll, so, if it is a troll please stop.
That's false, there are many companies using Chinese models in the US, Airbnb for example.
