Taiwan believes that NVIDIA chips may have been illegally transported to China through a transshipment route in Japan.

      Three individuals, including a senior vice president from Super Micro, have been charged with exporting US-restricted servers to Japan using fraudulent documents, which were then sent to mainland China. According to a Bloomberg report on Wednesday, Taiwanese prosecutors believe these suspects successfully smuggled at least one shipment of Nvidia AI chips to mainland China after routing them through Japan.

      This case marks Taiwan's inaugural public criminal prosecution concerning the diversion of AI chips and has significant implications for both Tokyo and Washington. The three suspects were apprehended 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 with US-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 US criminal indictment from March, which alleged that a broad $2.5 billion smuggling operation transferred Super Micro servers through a network spanning the US, Taiwan, Thailand, Hong Kong, and China.

      What is new in this week's Bloomberg report is the involvement of Japan. Taiwanese investigators now believe that at least one shipment utilized Japan as an intermediary transshipment point before the servers were sent to mainland China. Japan is not currently implicated as a willing participant in the alleged scheme; rather, it is suspected that the shipment was falsely declared as a legitimate export destined for Japan before being rerouted. Whether Japanese customs records validate this theory is a central question that Tokyo and Taipei are reportedly currently investigating together.

      This case exists within a broader context that has altered how Taipei views its export-control policies. The US has urged Taiwan over the past two years to take a more proactive stance in monitoring AI-chip exports to China; historically, Taiwan has been resistant due to its complex commercial ties to mainland China's semiconductor demand. This prosecution, being the first of its nature on the island, indicates a significant shift.

      Nvidia’s Jensen Huang has publicly stated that Chinese AI labs relying on smuggled or domestically sourced chips represent a strategic dilemma for the US, and the Taiwan case lends enforcement weight to this assertion.

      The involvement of Japan complicates the diplomatic scenario. Japanese authorities typically align with US export-control aims regarding advanced semiconductors and have tightened exports of domestic chipmaking equipment to China in alignment with US restrictions. Should the Bloomberg report prove accurate, and if chip-carrying servers were legitimately transshipped through Japan, Tokyo may face increasing pressure to tighten its own re-export regulations and to collaborate with Taipei in sharing intelligence about the specific routing networks involved. Additionally, Beijing's stance on AI talent and investment has hardened since 2026, resulting in heightened demand for smuggling with a high price tolerance.

      For Super Micro, the associated US criminal case continues to progress in New York; the company has indicated its cooperation with US authorities. Yih-Shyan Liaw remains a director, although Bloomberg has reported that the board has begun discussions regarding succession. The Keelung prosecutors’ office has yet to formally indict the three Taiwanese suspects, but the detention period is being prolonged as further evidence is sought.
