Micron Technology, a major US-based memory chip maker, is facing a probe by Chinese authorities over potential cybersecurity risks, in what appears to be retaliation against recent restrictions on technology sales to China by its allies.
The Cyberspace Administration of China has launched an investigation into Micron's products sold in the country, citing the need to ensure national security and prevent "hidden product problems" that could compromise key information infrastructure supply chains. The move comes as tensions between the US and China over tech exports continue to escalate.
Last month, Japan announced plans to restrict the export of advanced chip manufacturing equipment to countries including China, while the United States and the Netherlands have also imposed curbs on China's semiconductor industry. These moves are part of a broader effort by the US to limit China's access to critical technology and slow its emergence as a global tech powerhouse.
Micron has warned in an earlier filing that it faces risks from Chinese regulations, including potential restrictions on participation in the China market or prevention of effective competition with local companies. The company has stated that it is cooperating fully with the investigation and stands by the security of its products.
Shares in Micron plummeted 4.4% on Wall Street following news of the probe, their biggest drop in over three months. The company derives more than 10% of its revenue from China, making the move a significant concern for investors.
China has strongly criticized restrictions on tech exports, saying it "firmly opposes" such measures. However, Beijing is seeking to woo foreign investments and has been exerting pressure on companies to bring them into line with its agenda. In recent weeks, authorities have closed the offices of several foreign firms in China, detaining staff and imposing fines.
As tensions over tech exports continue to escalate, Micron's probe by Chinese authorities raises questions about the future of US-China relations and the potential impact on global supply chains.

 I mean, I get it, security concerns are valid, but let's not forget that trade wars can hurt a lot of people
 I mean, I get it, security concerns are valid, but let's not forget that trade wars can hurt a lot of people  especially those in China who rely on Micron's products. Hope the investigation finds out what's going on and resolves it soon
