DOJ arrests Californian over $300M Nvidia chip smuggling to China

Greg Lui, 38, was taken into custody on Thursday, 2 October 2026. He owns Earthmade Computer Inc in California.

Federal investigators say he orchestrated a massive scheme to move sensitive technology out of the United States. Court documents show the operation ran from October 2023 until at least August 2026. Prosecutors claim Lui received over $176 million in payments from two Malaysian transshipment companies. In exchange, he introduced them to US-based suppliers capable of providing Nvidia hardware. The total value of the kit involved is estimated at nearly $300 million. The hardware included servers with A100, H100, and GeForce RTX 5090 GPUs. These components are typically used for artificial intelligence development. The US government views such hardware as strategically vital. Assistant Attorney General for National Security John A. Eisenberg stated that "super intelligence" is the defining technology of the era. He added that the National Security Division will protect the American advantage in chips from illegal diversion by adversaries.

The $300 Million Scheme

Shipments were routed through countries that do not require Commerce Department licenses. Lui allegedly sent the hardware to Malaysia and Singapore first. Companies there would then forward the goods to China. Court documents cite a specific case where 92 servers were exported from San Francisco International Airport to Kuala Lumpur. The consignee for the onward re-shipment from Malaysia to Hong Kong was listed as a Chinese customer. The indictment alleges that Lui instructed a US front company to fraudulently list the recipient of a shipment. This tactic is designed to obscure the final destination from customs officials.

The scheme highlights the persistent difficulty in enforcing export controls against advanced semiconductor equipment. As long as high-value components remain in demand for AI training, the financial incentive for smuggling remains high. The arrest marks one of the largest known enforcement actions in this sector.

Policy and Espionage Context

This legal action coincides with broader tensions over technology transfer. On 4 October, The Hacker News reported on a China-aligned cyber espionage group known as TA419. Proofpoint, which analyzed the group, says TA419 has targeted AI policy experts in the US and Japan since April 2025. The group uses sophisticated phishing techniques, including a "Frameless BitB" attack, to steal credentials. The target of a recent campaign was an AI policy expert at a US think tank. The phishing email used the subject line "Request for Feedback on Military Integration of Claude." Proofpoint stated that this activity supports Chinese intelligence objectives to understand US AI policy developments. It occurs amid accusations of model distillation and export controls. The juxtaposition of physical smuggling and digital espionage illustrates a multi-vector approach to acquiring technological advantage. Both methods aim to neutralize US restrictions on advanced capabilities.

Institutional responses are tightening. On 4 October, the BBC reported that Queen's University Belfast asked staff to review partnerships with China. This followed a warning from MI5, the UK internal security service. MI5 identified the China General Technology Research Institute (CGTRI) as a front company for the Ministry of State Security. The agency warned that more than 100 UK-linked academics had contributed to projects funded by CGTRI. In some cases, researchers were unaware of the front company's role. MI5 stated that academics who fail to cut ties could face criminal charges for aiding a foreign state. The Chinese Embassy in London rejected the accusation, calling it "imaginary and purely fabricated." Queen's University, which has invested over $10 million in China-related research in the past decade, has commenced a review of existing collaborations.

The US is also attempting to reduce its own dependency on Chinese technology. CNN reported on 3 October that American companies are struggling to wean themselves off Chinese components. Rajat Bhageria, founder of Chef Robotics, described the challenge of building robots without Chinese parts. He noted that investors and customers are increasingly asking why companies still use foreign-made parts. Ben Armstrong, executive director of MIT's Industrial Performance Center, warned that decades of outsourcing have left US manufacturers ill-equipped to meet demand. He stated that the learning curve for domestic production will be steep and expensive.

This economic friction contrasts with the aggressive enforcement seen in the Lui case. The government is simultaneously trying to restrict Chinese access to US chips and US access to Chinese supply chains. The resulting policy landscape is complex and often contradictory. Companies face a dual threat: losing access to cheap components and facing legal risks if they attempt to bypass controls. The arrest of Greg Lui serves as a clear warning that enforcement is prioritizing the protection of AI hardware above all else. The $300 million figure highlights the scale of the illicit trade. It also highlights the continued global demand for the compute resources that power the latest generation of AI models. As export controls tighten, the black market for these components is likely to grow more sophisticated and harder to detect. The DOJ's action is a signal that the net is tightening around those who attempt to exploit the gaps in the current regulatory framework. The interplay between physical goods, digital espionage, and academic collaboration defines the current state of US-China technology policy. It is a conflict fought not just on the battlefield, but in courtrooms, server farms, and university labs.
