Hundreds of thousands of Nvidia AI chips have reached China through smuggling routes spanning Asia, Business Korea reports, underscoring the gap between US export controls and the chips' actual availability in the Chinese market.

The scale is striking. We are not talking about isolated back-channel deals but a sustained gray-market flow that has moved accelerators restricted by Washington into the hands of Chinese buyers. Nvidia's data-center GPUs, which the US government has barred from direct sale to China since escalating export controls in 2022 and 2023, remain the most sought-after hardware for training and running large AI models.

Asia serves as the transit hub. Chips initially sold into other markets in the region are diverted and reshipped to China, according to the report. This pattern complicates enforcement: components leave the United States or Nvidia's supply chain through legitimate channels, land with distributors or integrators elsewhere in Asia, and only then cross into China outside authorized trade.

The commercial stakes for Nvidia are considerable. China historically ranked among its largest markets, generating billions in data-center revenue before the controls took effect. Each smuggled unit represents demand the company cannot legally serve — and revenue that, from Nvidia's perspective, is captured by intermediaries rather than the vendor.

For Washington, the report highlights the limits of unilateral export enforcement. Restricting the shipment of high-performance accelerators does not eliminate Chinese demand for them; it redirects the flow through intermediaries and third countries. Whether the volume described — hundreds of thousands of units — prompts tighter tracking of end customers, stricter licensing for regional distributors, or diplomatic pressure on transit jurisdictions remains to be seen.

Chinese AI developers, meanwhile, continue to obtain the hardware they need to keep pace in model training, at least in part. That softens the intended effect of the controls, which aim to cap the compute available to Chinese AI programs, and it buys time for domestic accelerator efforts from Huawei and others to mature.

How effectively US authorities close these Asian transit routes will help determine whether export controls actually constrain Chinese AI compute — or simply reshape who profits from supplying it.
