Authorities in the United States have charged two Chinese citizens with shipping tens of millions of dollars’ worth of advanced Nvidia chips to China in breach of export controls.

Chuan Geng and Shiwei Yang are alleged to have “knowingly and willfully” exported the graphic processing units (GPUs) used to power artificial intelligence without authorisation from October 2022 to July 2025, the US Department of Justice said on Tuesday.

Export records indicate that Geng and Yang, both 28, organised at least 21 shipments through their El Monte, California-based company ALX Solutions Inc to companies in Singapore and Malaysia, the Justice Department said.
