- China's AI stocks fell Wednesday on news of the U.S. planning to impose more chip restrictions on China.
- China's CSI Artificial Intelligence Index slipped 3.76%. Inspur Electronic Information Industry Co Ltd and Chengdu Information Technology of Chinese Academy of Sciences slumped 10%.
- The Wall Street Journal report, which cited sources familiar with the matter, said that the curbs could come as quickly as next month to stop Nvidia and other chip makers from selling to customers in China.
China's artificial intelligence stocks fell Wednesday after the Wall Street Journal reported that the U.S. is planning to impose new curbs on shipments of AI chips to China.
According to the Journal, U.S. chip makers such as Nvidia will be affected by the move which could happen as early as July.
China's CSI artificial intelligence index fell 3% on that news on Wednesday in Asia. The Shenzhen-traded shares of Inspur Electronic Information Industry slumped 10% and Chengdu Information Technology of Chinese Academy of Sciences dropped nearly 8%. These firms primarily produce computers and software.
Other Chinese AI plays also fell. Hong Kong-listed shares of Alibaba — which launched its own version of the viral chatbot ChatGPT — dropped about 1.6%, and Tencent, which is building its own AI model, declined 1.58%.
Citing sources familiar with the matter, the WSJ said the U.S. has growing concerns about China's ability to make technological advancements with AI.
According to the report, the U.S. Commerce Department could "stop the shipments of chips made by Nvidia and other chip makers to customers in China and other countries of concern without first obtaining a license."
The Commerce Department did not immediately respond to CNBC's request for comments outside regular business hours.
Such a move will expand Washington's efforts to block China from advanced chip technology.
The U.S. implemented rules to cut China off from advanced chip equipment in October.
Washington also reportedly urged South Korea not to allow its domestic chip makers fill Micron's void in China.
Nvidia and another U.S. chip giant AMD have been barred by Washington since September from selling their advanced chips to China and Hong Kong.
To adhere to the export control rules, Nvidia reportedly started offering another advanced chip — the A800 — in China in November. The Journal report said the new curbs would ban the sale of A800 chips to China without a special U.S. export license.
However, Reuters recently reported that Nvidia's advanced A100 chips are being sold discreetly at China's underground markets at $20,000 each — double of its usual price.
Nvidia shares are up 187% year-to-date while AMD shares are higher by 70.4% in the same period.
