see #1. China doesn't really have their supply-chain of their own. SMIC's 7nm in particular runs on ASML DUV's.

China's most advanced litho maker is SMEE. It was reported that their most cutting-edge node 28nm would be mass-produced this year, but don't hold your breath -- they've been saying it for at least a couple of years now.

SMIC's 7/5nm use ASML's Twinscan NXT:2000i deep ultraviolet DUV. According to SCMP, SMIC can import them until 2024 as the new restriction in the Netherland/Japan doesn't kick in until then.
