I’m sceptical they could find the legal framework to do this even if they wanted to
They have legal authority to (a) prevent export of US goods/services; (b) ban imports of physical goods; (c) ban transactions (including purchasing services or license agreements) with foreign firms
But I’m not aware of any legal authority which lets them ban US firms from running a Chinese-developed open source AI model in the United States, if they are at arms length from the vendor, and aren’t using it for government contracts or regulated applications
Possibly they could order HuggingFace/etc to suspend Chinese accounts. But if someone in the US (or a third country) downloads the model from China then reuploads it to a US server, completely independently of the vendor - where is the legal hook to prohibit that?
