Chinese semiconductor stocks climbed following reports that sales of Nvidia’s H200 chips are facing restrictions

Chinese semiconductor shares climbed on Wednesday after reports said Beijing will restrict purchases of Nvidia’s H200 AI chips to limited, special-use cases. The news largely outweighed an earlier announcement that the U.S. had cleared sales of the H200 to China.

Shares of Semiconductor Manufacturing International Corp, the country’s largest chipmaker by output, rose nearly 2% in Hong Kong, while Hua Hong Semiconductor gained almost 5%. On the mainland, Cambricon Technologies and Moore Threads Technology—both promoted as domestic alternatives to Nvidia—also advanced.

According to The Information, Chinese authorities have told local technology firms that H200 purchases will only be approved under exceptional circumstances, such as for university research and development facilities. This development muted the impact of the U.S. Commerce Department’s decision to allow H200 exports to China, a move previously hinted at by President Donald Trump in late December and accompanied by strict conditions.

Beijing is seen as taking a cautious approach to the approval as it continues to pursue full self-reliance across the artificial intelligence supply chain, with chip manufacturing playing a central role due to the heavy computing demands of AI development and deployment. Although China made progress in chip production in 2025, it is still widely regarded as far from achieving complete technological independence.

Chinese technology stocks have advanced over the past week, driven by a wave of high-profile IPOs from leading domestic AI companies that boosted confidence in the sector’s growth outlook. The rally extended on Wednesday, with MiniMax Group and Zhipu—listed as Knowledge Atlas— the first of China’s so-called “AI tigers” to go public, climbing 4.4% and 17%, respectively.
