China’s CAC Bans Critical Infrastructure Operators from Buying Micron Technology Products

China’s Cyberspace Administration (CAC) has banned the country’s critical information infrastructure operators from buying products from US chipmaker Micron Technology, citing serious network security risks and potential security threats to the country’s national security.[0] Micron is the first US chipmaker to be targeted by Beijing following a series of export controls by Washington on certain US components and chip-making tools to block them from being used to advance China’s military capabilities.[1] While Micron has said it is evaluating the CAC’s conclusion and assessing its next steps, Jefferies analysts expect the ban to have limited impact on the company, as its major customers in China are consumer electronics firms such as smartphone and computer manufacturers, not infrastructure suppliers.[2]
