Nvidia has firmly denied Chinese government accusations that its AI chips contain kill switches or backdoors, reiterating in multiple blog posts that its GPUs have no such features. The company emphasized that incorporating kill switches or backdoors would undermine trust in U.S. technology and pose cybersecurity risks. Meanwhile, the U.S. Department of Justice charged two Chinese nationals, Chuan Geng and Shiwei Yang, residing in California, with illegally exporting tens of millions of dollars' worth of advanced Nvidia AI chips, including H100, RTX 4090, and 5090 GPUs, to China from October 2022 through July 2025. The shipments were reportedly routed through Malaysia and Singapore to obscure their destination, violating U.S. export controls. In a related development, Nvidia CEO Jensen Huang met privately with former President Donald Trump at the White House shortly before Trump announced sweeping new tariffs on semiconductor imports. Following this meeting, the U.S. Commerce Department began issuing licenses allowing Nvidia to export its H20 AI chips to China, reversing earlier restrictions. Nvidia has urged U.S. policymakers to avoid mandating backdoors or kill switches in its products, warning such measures would be a "gift" to hackers and hostile actors and damage the integrity of digital infrastructure.
