China has launched a cybersecurity probe into Micron Technology, one of the US's largest memory chip makers, as tensions between Washington and Beijing escalate over restrictions on China's semiconductor industry.
The move comes as the Cyberspace Administration of China (CAC) reviews products sold by Micron in the country, aimed at "ensuring the security of key information infrastructure supply chains, preventing cybersecurity risks caused by hidden product problems, and maintaining national security". This appears to be a response to new restrictions announced by US allies Japan and the Netherlands on the sale of advanced chip manufacturing equipment to China.
The probe is part of a broader effort by Beijing to exert pressure on foreign companies to bring them into line with its agenda. Last month, authorities closed the Beijing office of a US corporate intelligence firm and detained staff, while days earlier they suspended Deloitte's operations in Beijing for three months over allegations of lapses in auditing work.
Micron has warned in an earlier filing that such risks exist and has said it stands by the security of its products. However, shares in the company have plummeted 4.4% on Wall Street following the news, with the biggest drop in more than three months. Micron derives over 10% of its revenue from China.
China has strongly criticized restrictions on tech exports, saying last month it "firmly opposes" such measures. Beijing is seeking to woo foreign investments as it grapples with mounting economic challenges and is offering a "good environment and services" to global CEOs.
The escalating tensions between the US and China over technology are seen as part of a broader trade war. Washington has banned Chinese companies from buying advanced chips and chip-making equipment without a license, while Beijing has retaliated with its own restrictions on US tech exports.
