Tensions in the ongoing U.S.-China artificial intelligence rivalry have escalated once again, after Taiwanese prosecutors levied criminal charges Monday against nine individuals tied to top global tech firms for smuggling restricted high-end AI hardware into mainland China. The defendants include one current employee of leading chip designer Nvidia and two former workers of U.S.-based server manufacturer Super Micro Computer, according to official prosecutorial documents.
Advanced AI infrastructure, which relies heavily on cutting-edge semiconductors produced primarily in Taiwan, has emerged as the central battleground for technological and economic competition between Washington and Beijing. The U.S. first implemented sweeping restrictions on Nvidia’s exports of top-tier AI chips to mainland China in 2022, tightening the regulations in subsequent years to block access to hardware that could advance China’s military and domestic AI development. Most recently, in April 2025, the Biden administration mandated that all exports of Nvidia’s H20 AI chips to China require special government approval, only partially reversing the rule to allow limited shipments later the same year.
Per guidelines outlined by the Keelung District Prosecutors’ Office in northern Taiwan, all sales of high-end AI servers — the specialized computing systems that host the powerful graphics processing units (GPUs) that power large-scale generative AI models — to parties linked to mainland China are subject to rigorous export control reviews. Regulations also require that any bulk purchase of more than eight high-end AI servers must be preceded by in-person compliance checks of the end client by company staff to verify the final destination and use case.
Prosecutors confirmed that the restricted hardware at the center of the smuggling ring is Nvidia’s B300 GPUs, a high-end AI chip model that is explicitly banned from commercial sale to mainland China under current export rules. Investigations found that the ring successfully smuggled 74 B300-powered AI servers into mainland China via multiple layered smuggling routes to avoid detection: 50 units were transshipped through Indonesia, 16 were sent directly to Chinese ports, and an additional eight were first routed to Japan, then transferred to Hong Kong before being moved across the border to the mainland. A separate attempted shipment of 56 more banned servers was intercepted before it could leave Taiwan, and the hardware remains in custody of local authorities.
Among the nine charged defendants, four — including a senior Nvidia manager identified only by his surname Chang — are being pursued for the maximum possible five-year prison sentence under Taiwanese export control laws. Prosecutors labeled Chang the “key mastermind” of the scheme, noting he bore direct responsibility for authorizing the release of the restricted B300 GPUs for shipment, and has not cooperated with investigations following his arrest. Court documents also detail that multiple conspirators set up a front company in Japan to facilitate the shipment of eight servers, while others created fraudulent business websites and falsified end-user documentation to trick compliance screenings and evade border checks.
In an official written statement responding to the charges, Nvidia spokesperson Patrick Rutherford said the company is committed to collaborating with Taiwanese regulatory and prosecutorial authorities to resolve the allegations as quickly as possible. Super Micro, meanwhile, noted in its own statement that the two former employees arrested in the case were identified during the company’s own cooperation with Taiwanese investigations. The company added that it will continue to upgrade its internal export compliance protocols “to protect American innovation”, in line with U.S. regulatory requirements.
The charges mark the latest high-profile enforcement action against illegal tech smuggling amid growing global scrutiny of AI hardware flows to China, as the U.S. doubles down on efforts to limit China’s access to cutting-edge AI technology.
