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.
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.
