Taiwanese prosecutors have indicted nine people for allegedly forging documents to disguise the illegal export of high-end AI servers to China, a scheme that reportedly involved an Nvidia senior manager and two Supermicro employees based in Taiwan. The charges—breach of trust and document forgery—stem from an investigation launched after US authorities arrested Supermicro co-founder Wally Liaw in March for allegedly funneling $2.5 billion in restricted AI servers to China since 2024.

The scheme’s mechanics were brazen. According to Reuters, co-conspirators tried to make it look like 130 B300 servers were installed and running at a Taiwan facility. In reality, 74 of those servers ended up in the hands of Chinese customers before customs officials caught on. The remaining 56 were blocked after Taiwanese customs “detected irregularities”—a bureaucratic phrase for what was likely a close call. One suspect linked to a related case remains at large, accused of siphoning funds from a distributor company involved in the operation.

Since 2022, Washington has required licenses to export advanced semiconductors to China, part of an escalating effort to keep the US ahead in the AI race. The B300—Nvidia’s latest Blackwell-generation chip—is exactly the kind of hardware that restriction targets. The fact that someone inside Nvidia allegedly helped forge documents to move these servers underscores a persistent vulnerability: export controls are only as strong as the people implementing them.

Supermicro, for its part, says it’s cooperating with Taiwanese investigators and remains “committed to protecting our advanced technologies and intellectual property.” But the arrest of its own co-founder in March, followed now by indictments of two more employees, suggests the problem runs deeper than a few bad actors. Meanwhile, Nvidia didn’t respond to requests for comment. The question now is whether this was an isolated ring or evidence that Taiwan—the epicenter of advanced chip manufacturing—has become a chokepoint that smugglers have learned to exploit.
