I'm more talking the 1.4 billion people in China that need CPUs when you try to tell them they can't use ARM or RISC or etc. not the 330 million in the US that want something manufactured. We've already import restricted Android devices from e.g. Huawei, it has had no impact to their need for CPU designs for them though.

So if it is their internal market, because of how big they are, there is nothing that you can do unfortunately. Only impose further sanctions that will eventually escalate to a war. In that sense China won, because no country can afford to stand up against them in a meaningful way.
