China says US chipmaker Micron failed national security review

Beijing: US semiconductor giant Micron has failed a national security review, China’s cybersecurity watchdog said Sunday, telling operators of “critical information infrastructure” to stop buying its products.

It marked the latest escalation in the bitter chip war between the United States and China, with Washington looking to cut off Beijing’s access to cutting-edge semiconductors.

Chinese authorities launched a review in March of products sold in the country by Micron, one of the world’s major chip manufacturers.

Micron’s products “have relatively serious potential network security issues, which pose a major security risk to China’s critical information infrastructure supply chain and affect China’s national security”, the cybersecurity administration (CAC) said in a statement.
