Taiwan believes that NVIDIA chips were illicitly transported to China through a transshipping route in Japan.

      Three suspects, including a senior vice president of Super Micro, are charged with exporting U.S.-restricted servers using false documents to Japan and subsequently to mainland China. Taiwanese prosecutors suspect that these individuals successfully smuggled at least one shipment of Nvidia AI chips to mainland China after first exporting them to Japan, according to a Bloomberg report on Wednesday quoting sources familiar with the investigation.

      This case marks Taiwan’s first public criminal prosecution concerning AI-chip diversion and carries significant implications for both Tokyo and Washington. The three suspects were arrested last week by Taiwan’s Keelung District Prosecutors Office. They are accused of falsifying export-declaration documents to hide the fact that Super Micro Computer servers containing U.S.-restricted Nvidia chips were ultimately intended for China.

      The individuals named are Yih-Shyan “Wally” Liaw, a senior vice president of business development at Super Micro and a board member, Ruei-Tsang “Steven” Chang, a sales manager based in Taiwan, and Ting-Wei “Willy” Sun, a contractor. All three were initially mentioned in a U.S. criminal indictment from March, which alleged a broader $2.5 billion smuggling ring that moved Super Micro servers through a network spanning the U.S., Taiwan, Thailand, Hong Kong, and China.

      New information from this week's Bloomberg report highlights the Japan aspect. Taiwanese investigators now believe that at least one shipment was routed through Japan as an intermediate point before being sent to mainland China. Japan is not currently identified as an active participant in the alleged scheme; the suspicion is that the shipment was declared as a legitimate export destined for Japan and then diverted. The key question that Tokyo and Taipei are reportedly examining together is whether Japanese customs records align with this theory.

      This case takes place within a broader context that has changed Taipei's approach to its export-control policies. Over the past two years, the U.S. has urged Taiwan to take a more active role in monitoring AI-chip exports to China; however, given its complicated commercial relationship with mainland Chinese demand for semiconductors, Taiwan has historically resisted. This prosecution, the first of its kind on the island, indicates a significant shift.

      Nvidia’s Jensen Huang has publicly stated that Chinese AI labs utilizing smuggled or domestically produced chips present a strategic problem for the U.S.; the Taiwan case adds a layer of enforcement to that argument.

      The involvement of Japan complicates the diplomatic landscape. Japanese authorities generally align with U.S. export-control goals regarding advanced semiconductors and have tightened exports of domestic chipmaking equipment to China in accordance with U.S. restrictions. If the Bloomberg report holds true and chip-laden servers were genuinely transshipped through Japan, Tokyo will likely face pressure to strengthen its own re-export controls and to collaborate with Taipei on intelligence regarding the specific routing networks involved. Beijing's internal stance on AI talent and investment has also intensified in 2026, creating a high demand with significant price tolerance for smuggling operations.

      For Super Micro, the related U.S. criminal case is ongoing in New York, and the company has stated that it is cooperating with U.S. authorities. Yih-Shyan Liaw remains a director, although Bloomberg has previously reported that the board has started discussing succession. The Keelung prosecutors’ office has not formally indicted the three Taiwanese suspects, but the detention period is being extended as further evidence is pursued.
