Rep. Brian Mast is escalating Washington’s fight over artificial intelligence hardware, accusing Nvidia and its chief executive Jensen Huang of helping arm China’s military through sales of cutting edge chips. His charge lands just as President Donald Trump’s administration clears a path for Nvidia’s latest H200 processors to reach Chinese buyers under new export guardrails, sharpening a clash between national security hawks and a company that has become the world’s most important AI supplier.
At stake is more than a single product line. The dispute goes to the heart of how the United States should treat advanced AI accelerators that can power everything from consumer apps to nuclear targeting models, and whether existing export controls are enough to keep those capabilities out of Beijing’s defense ecosystem.
Mast’s allegation: AI chips as military hardware
Rep. Brian Mast, a military veteran and chair of the House Foreign Affairs Committee, is not just criticizing Nvidia’s business strategy, he is arguing that the company is effectively strengthening the Chinese armed forces. In his telling, Nvidia and Jensen Huang are selling advanced AI chips to Chinese entities that he describes as “military linked firms,” a pattern he frames as direct support for the People’s Liberation Army and its modernization drive, according to Mohd Haider. He is using his platform to argue that what looks like commercial export activity is, in practice, a transfer of battlefield capability to a strategic rival.
Those accusations are part of a broader message Mast has been delivering on Capitol Hill, where he has warned colleagues that “not every chip sale is a military sale” but “many of them are,” a line that underscores his belief that AI accelerators should be treated more like weapons than like generic semiconductors, as reflected in his committee remarks. In his view, the United States cannot afford to assume that Chinese buyers will keep Nvidia’s most capable products confined to civilian cloud services when the same hardware can train models for hypersonic missiles, autonomous drones, or cyber operations.
A political fight over Trump’s export greenlight
Mast’s rhetoric is colliding with a major policy shift from the Trump administration, which has just approved a new framework for Nvidia Corp to resume shipments of its H200 AI chips to China. Under revised criteria, U.S. officials are allowing exports of the H200 as long as companies comply with performance thresholds and other conditions that are meant to keep the most sensitive capabilities out of Chinese hands, according to new rules. Supporters of the move argue that carefully calibrated guardrails can preserve U.S. commercial leadership while still constraining Beijing’s access to the very top tier of AI performance.
Critics in Congress, including Mast, see something very different. They argue that once H200 shipments restart, even under limits, China will still gain access to a class of accelerators that can be clustered into supercomputers and repurposed for military research. The Trump administration’s approval to resume exports has already drawn bipartisan fire, with lawmakers warning that the line between commercial AI and warfighting AI is far thinner than the regulatory language suggests.
Nvidia’s defense: compliance, demand, and a booming stock
Jensen Huang has been pushing back hard on Mast’s narrative, arguing that Nvidia is already operating under a dense web of export rules and does not need a new layer of bespoke legislation. In LAS VEGAS, the Nvidia CEO told reporters that he opposed a bill from House Foreign Affairs Committee Chair Brian Mast, suggesting that the existing “laws I think is plenty” and that additional restrictions risk undermining U.S. competitiveness without meaningfully changing China’s trajectory, according to his comments in LAS VEGAS. From Huang’s perspective, Nvidia is following Washington’s rules, not writing them, and should not be singled out as a villain for selling what the government itself has cleared.
Market signals suggest investors are siding, at least for now, with Nvidia’s growth story rather than Mast’s warnings. NVDANVIDIA Corp is trading around $186.250, a price that reflects both the company’s dominant share of AI accelerators and expectations that demand from cloud providers, enterprises, and international buyers will remain intense, according to market data. Huang has also been courting Republican lawmakers directly, telling them he shares concerns about the AI race with China while arguing for “controls on AI exports” that are targeted rather than sweeping, a message he delivered during a visit described as Nvidia CEO Jensen.
How China fits into the AI chip race
Behind the Mast–Nvidia clash is a simple reality: China is a massive and growing market for high performance AI chips, and Nvidia has been racing to serve it within the bounds of U.S. law. Nvidia CEO Jensen Huang has said the company is seeing “very high” interest in its H200 chip from China customers, describing potential demand that could reach tens of billions of dollars per year, according to his comments on China customers. For Beijing, access to such hardware is central to ambitions in everything from industrial automation to surveillance and military planning.
That is why Mast and other hawks argue that “the outcome of this race directly affects military competitiveness of the United States of America versus China,” a framing that treats AI chips as a core determinant of future power balances rather than just another export category, as he has warned in public remarks. When critics say that selling H200s to China “will supercharge Beijing’s military modernization, enhancing capabilities in everything from nuclear weapons to cyberwarfare,” they are drawing a straight line from Nvidia’s order book to China’s strategic arsenal, a link that Mast is now trying to codify into law.
Inside Mast’s legislative push and the broader oversight debate
Mast is not limiting himself to speeches. As Military Veteran Rep, he has introduced legislation that would tighten controls on AI chip exports and potentially restrict Nvidia’s ability to sell to Chinese buyers that he views as too close to the People’s Liberation Army, a move that has been described as Mast Accuses Nvidia, Jensen Huang Of Selling Advanced AI Chips To Chinese Military, Linked Firms in recent coverage. He has also accused some colleagues of being too cozy with Nvidia, suggesting that members who echoed the company’s talking points “were promoting Nvidia’s agenda,” a charge leveled directly at Brian Mast (R-Fla.) in accounts that describe how he has clashed with fellow Republicans over the issue, as reflected in committee disputes.
His campaign is unfolding against a backdrop of broader concern in Washington that “our secretary demands 21st century technological supremacy in AI, hyper sonics and drones” and that congressional oversight “needs to keep pace with that,” as one hearing summary put it in describing the Pentagon’s expectations and lawmakers’ responsibilities, according to Our secretary. For Mast, that means treating Nvidia’s H200 and similar accelerators less like generic “product” lines and more like dual use systems that require the same level of scrutiny as advanced missiles or stealth aircraft, even if they are sold through ordinary commercial channels that look, at first glance, like any other product.
