The Chinese government has told operators of important infrastructure in the country to stop buying products from the US chipmaker Micron Technology.
Its products carry “serious network security risks” that pose hazards to China’s information infrastructure and affect national security, the Cyberspace Administration of China said in a statement on its website.
The move is the latest example of tensions between the US and China over technology, after a US ban on using the social video app TikTok on government phones and restrictions imposed by Washington on the export of some sophisticated computer chips to China.
“Operators of critical information infrastructure in China should stop purchasing products from Micron,” the Chinese agency said on Sunday. A US Department of Commerce spokesperson said the move had “no basis in fact”. The China and Hong Kong market accounts for about 15% of revenues at Micron, and the company’s shares dropped 3.7% in early trading in New York.
It generated $5.2bn (£4.2bn) of revenue from China, including $1.7bn from Hong Kong last year, about 16% of its total revenue, according to Jefferies.
Last year the U.S. government banned the export of cutting-edge chips, including artificial intelligence chips and specific GPUs from companies like AMD and Nvidia, to China also U.S blacklisted top Chinese memory chip maker YTMC.
