Official China government statement says Micron's products "pose a major security risk."
An official statement published by the Cyberspace Administration of China (CAC) says that operators of critical information infrastructure "should stop purchasing Micron products." The decree, spotted by Wen-Yee Lee, comes after a network security review of Micron's products sold in China.
Apparently, the Chinese government security review found that "Micron's products have relatively serious potential network security issues, which pose a major security risk to my country's critical information infrastructure supply chain." However, no detail of any specific security risks presented by the usage of Micron products is given. As a matter of "national security," we assume the Micron products ban will be implemented swiftly and thoroughly.
At the end of its statement, the CAC asserts that all companies from all countries are welcome to enter the Chinese market, as long as they abide by local laws and regulations. Again, there is no hint given about how the US-based Micron has broken any regulations.
