CAS XiangShan RISC-V:CAS is working with top Chinese companies, including Alibaba, Tencent, and ZTE, to co-develop XiangShan-v3, which will match the performance of ARM’s Neoverse-N2 server CPU design, which ARM announced in 2021.
https://news.slashdot.org/story/23/10/0 ... technologyAn anonymous reader shared this report from Reuters: In a new front in the U.S.-China tech war, President Joe Biden's administration is facing pressure from some lawmakers to restrict American companies from working on a freely available chip technology widely used in China — a move that could upend how the global technology industry collaborates across borders... RISC-V can be used as a key ingredient for anything from a smartphone chip to advanced processors for artificial intelligence... The lawmakers expressed concerns that Beijing is exploiting a culture of open collaboration among American companies to advance its own semiconductor industry, which could erode the current U.S. lead in the chip field and help China modernize its military. Their comments represent the first major effort to put constraints on work by U.S. companies on RISC-V... Executives from China's Huawei Technologies have embraced RISC-V as a pillar of that nation's progress in developing its own chips. But the United States and its allies also have jumped on the technology, with chip giant Qualcomm working with a group of European automotive firms on RISC-V chips and Alphabet's Google saying it will make Android, the world's most popular mobile operating system, work on RISC-V chips... Jack Kang, vice president of business development at SiFive, a Santa Clara, California-based startup using RISC-V, said potential U.S. government restrictions on American companies regarding RISC-V would be a "tremendous tragedy." "It would be like banning us from working on the internet," Kang said. "It would be a huge mistake in terms of technology, leadership, innovation and companies and jobs that are being created." One U.S. Representative said the Chinese Communist Party was "abusing RISC-V to get around U.S. dominance of the intellectual property needed to design chips. "U.S. persons should not be supporting a PRC tech transfer strategy that serves to degrade U.S. export control laws."

They are not allowed to ship these machines to China because they contain a lot of American tech. It will take a lot longer than 3 years before China catches up.
--But less advanced DUV models can be retooled with deposition and etching gear to produce 7-nanometer and possibly even more advanced chips, according to industry analysts.
Huawei now lists a chip made on a 5nm-class process node — an eight-core Arm-based HiSilicon Kirin 9000C processor with Arm Mali-G78 graphics for laptops — on its website.

As far as I got it, they have a home-grown 28nm process and imported 14nm/10nm DUV while not on the black-list. People thought they need EUV technology to go sub 10nm, but now the speculation goes that they found a way to use DUV for 7nm and 5nm fab process (multi-patterning). These nm numbers do not reflect real scales but represent transistor density|efficiency of fab process*. Question is open about the yield rate and the costs of such an technique and how much further they can go. Further it was said that China uses multi-chip modules, for scaling of chips with larger fab process.

I can imagine that this is just a beginning, or alike.
