China delivered the latest salvo in an escalating semiconductor war with the U.S., announcing that Micron Technology products have failed to pass a cybersecurity review in the country.

In a statement Sunday, Beijing warned operators of key infrastructure against buying the company¡¯s goods, saying it found ¡°relatively serious¡± cybersecurity risks in Micron products sold in the country.

The components caused ¡°significant security risks to our critical information infrastructure supply chain,¡± which would affect national security, according to the statement from the Cyberspace Administration of China, or CAC.
