Operation Gatekeeper exposes sophisticated effort to reroute export-controlled GPUs to China despite sweeping U.S. restrictions
MARKET INSIDER – U.S. federal prosecutors have dismantled a sprawling China-linked smuggling network that trafficked or attempted to traffic more than $160 million worth of restricted Nvidia AI chips, marking one of the largest export-control busts since Washington tightened limits on China’s access to advanced semiconductors.
The investigation — Operation Gatekeeper — revealed a coordinated, multi-layer effort to funnel Nvidia’s H100 and H200 GPUs, which require special export licenses, to China, Hong Kong and other prohibited destinations. Authorities say the chips, prized for both military and commercial AI development, were disguised through falsified documents, straw purchasers and relabeled shipments to evade U.S. scrutiny.
Alan Hao Hsu, 43, and his Texas-based firm Hao Global LLC have already pleaded guilty. Prosecutors say Hsu’s network moved or attempted to move over $160 million in controlled GPUs between late 2024 and May 2025, supported by more than $50 million in China-sourced funding. He faces up to 10 years in prison at sentencing in February.
Two additional defendants — New York-based tech owner Fanyue Gong and Canadian executive Benlin Yuan — were charged for separate schemes involving covert procurement, warehouse relabeling, false documentation and coordinated efforts with Hong Kong and China-based partners to bypass export controls. Yuan faces up to 20 years if convicted.
Nvidia said it is working with authorities to combat second-hand chip smuggling, warning that even older-generation GPUs remain tightly regulated.
The crackdown comes amid a series of similar busts as Washington intensifies enforcement of semiconductor export bans designed to slow China’s AI and military modernization. At the same time, geopolitical calculations are shifting: the U.S. president signaled this week that Nvidia will be permitted to ship H200 chips to “approved customers” in China — but only if Washington receives 25% of the proceeds.
While the H200 is no longer Nvidia’s most advanced GPU, it would instantly become the highest-performance chip legally accessible to China, potentially easing the country’s acute AI compute shortage even as authorities race to shut down illicit routes.
The latest case highlights both the scale of the global gray market for AI hardware and the increasingly complex cat-and-mouse game between U.S. regulators and networks determined to circumvent export rules.
