China’s Cyberspace Administration (CAC) has announced that America’s largest memory manufacturer poses “serious network security risks.”
This means the firm’s chips will be banned from major infrastructure projects in the world’s second largest economy.
As tensions escalate between Beijing and Washington, the move is China’s first major move against a US chip maker.
“The review revealed that Micron products pose serious network security risks that pose significant security risks to China’s critical information infrastructure supply chain and affect China’s national security,” the China Cyberspace Administration said in a statement.
CAC did not disclose the details of the risks it said it found or which Micron products it found them.
A Micron spokesperson confirmed to the BBC that the company “received CAC’s notice after it reviewed Micron products sold in China”.
“We are evaluating the outcome and our next steps. We look forward to continuing talks with the Chinese authorities,” the statement said.
