China's Ban on Micron Chips Raises National Security Concerns.

China has banned some sales of Micron products, citing cybersecurity risks and posing a big risk to the country’s key information supply chains. The decision is seen as part of the ongoing U.S.-China economic competition, which has started to upend a deeply intertwined global tech supply chain. Micron is the third-largest market in China, accounting for 10.7% of its annual revenue in 2022. The ban could benefit Micron’s competitors in China, the South Korean giants Samsung Electronics and SK Hynix.
