A unit of telecoms gear maker ZTE Corp and two other Chinese firms are among the latest entities to receive U.S. approval to purchase advanced AI chips from Nvidia and AMD, according to documents and two sources familiar with the matter. ZTE Kangxun Telecom and server maker Maginfra have been permitted to purchase Nvidia's H200 chips, while Zhuhai Hengqin Yunxiang Zhisheng Network Technology, a subsidiary of cloud computing company Kingsoft, has been cleared to use some AMD chips that rival the H200. The three firms expand the known set of companies involved in the licensing process beyond China's largest internet groups and major electronics distributors. Reuters reported in May that the U.S. had cleared around 10 Chinese firms, including Alibaba, Tencent, ByteDance and JD.com, to buy the Nvidia chips, but that no deliveries had been made at that time. However, some Chinese cloud firms have recently told partners and clients they may soon be able to obtain H200 chips, the sources said, indicating some progress in import reviews by Chinese authorities.
