Chinese chips advance despite being shut out of US technology

Alibaba shares rose after it unveiled what it called China’s most powerful chip ever. 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.
