Micron Technology, one of America's largest memory chip makers, is under scrutiny from China's Cyberspace Administration in a move that appears to be retaliation against US allies in Asia and Europe who have announced new restrictions on the sale of key technology to Beijing.
The probe, launched late Friday, aims to "ensure the security of key information infrastructure supply chains, prevent cybersecurity risks caused by hidden product problems, and maintain national security." Micron has warned earlier that it may face challenges selling its products in China due to the country's strict regulations.
The US has banned Chinese companies from buying advanced chips and chip-making equipment without a license, while Japan has restricted the export of advanced chip manufacturing equipment to countries including China. The Netherlands has also unveiled new restrictions on overseas sales of semiconductor technology, citing national security concerns.
Shares in Micron dropped 4.4% on Wall Street following the news, their largest decline in over three months, with shares closing another 1.2% lower on Monday. The company derives more than 10% of its revenue from China and has previously warned of such risks.
In an earlier filing, Micron had said that "the Chinese government may restrict us from participating in the China market or may prevent us from competing effectively with Chinese companies." This is in line with Beijing's growing pressure on foreign companies to bring them into line with its agenda.
China has strongly criticized restrictions on tech exports, saying it "firmly opposes" such measures. However, Beijing continues to exert pressure on foreign companies, with authorities closing the Beijing office of a US corporate intelligence firm and detaining staff last month.
