The Chinese leader's message in San Francisco got the attention of U.S. officials because it was delivered at a meeting that was intended to reduce tensions.
They didn’t move them, they’re just building new fabrication plants here so we don’t have to depend on threatened foreign land for the production. https://pr.tsmc.com/english/news/2977
Also SMIC (China’s chip manufacturer) is now also producing 7nm chips, even though they were sanctioned in 2020. That means they either had a breakthrough in the process or they obtained and were able to repair and operate/reverse engineer the incredibly complex TSMC fabs.
7nm doesn’t need EUV, as things get smaller it doesn’t suddenly become impossible to do things with traditional lithography it just becomes harder and at some point incredibly uneconomical. They certainly ripped off the node from TSMC in some way (whether spionage or reverse-engineering), that is, the shape of the transistors and stuff but that doesn’t mean that they’re producing them in the same way.
