Chinese chips advance despite being shut out of US technology

retained text

Chinese tech firms showcased advances in chipmaking, despite US curbs on access to cutting-edge semiconductor technology.
Alibaba shares rose after it unveiled what it called China’s most powerful chip ever, part of a bid to expand across the hardware and software components of the AI ecosystem. Its announcement came just days after memory chipmaker CXMT — which is fast winning domestic market share from global giants Samsung and SK Hynix — said its latest chip platform was entering mass production.
Researchers are making inroads at the cutting edge, too: Chinese Academy of Sciences scientists said they had made progress in using older technology to build highly advanced chips, a potential workaround to US restrictions on accessing advanced semiconductor manufacturing equipment.
