National Security Leaders Urge U.S. to Block Nvidia H20 Chip Sales to China

Key Takeaways:

• Twenty former U.S. national security officials have urged the government to block Nvidia’s H20 chip sales to China.
  

• The H20 chip is optimized for AI inference and used to power frontier models, raising concerns about its strategic value.
  

• The experts called the policy reversal a “strategic misstep” and warned of military and surveillance applications.
  

• The Trump administration had previously restricted H20 exports but recently lifted the ban.
  

• The group argues that allowing sales could weaken U.S. export controls and empower China’s AI development.

National Security Experts Oppose Nvidia Chip Sales to China

A group of 20 national security experts and former U.S. officials is urging the U.S. government to stop Nvidia from exporting its H20 AI chip to China. In a formal letter to the Department of Commerce, the group described the administration’s recent policy reversal as a “strategic misstep” that could harm the country’s long-term advantage in AI and military technologies.

The H20 chip is designed for AI inference, the process of using a trained AI model to make decisions on unseen data. Experts argue that the chip is powerful enough to be used in surveillance systems, autonomous weapons, and other dual-use technologies that could benefit China’s military and state-controlled AI initiatives.

The timing of the letter coincides with the Department of Commerce approved renewed H20 chip sales as part of ongoing trade discussions with China over rare earth elements. At the time, Commerce Secretary Howard Lutnick downplayed the impact, calling the H20 Nvidia’s “fourth best” AI chip.

“The H20 is a potent accelerator of China’s frontier AI capabilities, not an outdated AI chip,” the letter stated. “Designed specifically to work around export control thresholds, the H20 is optimized for inference, the process responsible for the dramatic capabilities gains made by the latest generation of frontier AI reasoning models. For inference tasks, the H20 outperforms even the H100, an AI chip this administration has restricted access to due to its advanced capabilities.”

The letter was signed by several former senior officials, including Matt Pottinger, former deputy national security adviser; Stewart Baker, former assistant secretary of Homeland Security under President George W. Bush; and David Feith, a former member of the National Security Council.

Reversal Raises Alarm Over U.S. Export Policy

The U.S. had previously restricted exports of the H20 chip to China as part of a broader strategy to limit access to high-performance AI hardware. That ban was recently lifted, allowing Nvidia to resume sales of the chip in the Chinese market. The move has sparked backlash from the national security community, who say the decision undermines existing export controls.

In their letter, the signatories warned that easing restrictions on a chip as capable as the H20 sends mixed signals and reduces the effectiveness of broader efforts to contain China’s AI ambitions. The group emphasized that the H20 is not a compromised or low-end product, but a chip designed to accelerate state-of-the-art AI systems.

It also follows the Trump administration’s release of its AI Action Plan last week, which emphasized the need for stronger AI chip export controls but offered few specifics on how such restrictions would be implemented.

Strategic Stakes for the U.S. and AI Leadership

The call to reimpose restrictions reflects broader concerns about the role of semiconductors in geopolitical competition. AI chips are no longer seen as neutral computing tools—they are now viewed as foundational infrastructure for national competitiveness. Allowing a powerful chip like the H20 into Chinese hands, the experts argue, risks handing over an advantage that is difficult to reclaim.

The letter also reflects a growing divide between economic priorities and national security strategy, with some policymakers favoring tech sector growth and others pushing for tighter controls to safeguard U.S. leadership in critical technologies.

“The decision to ban H20 exports earlier this year was the right one,” the letter said. “We ask you to stand by that principle and continue blocking the sale of advanced AI chips to China as America works to maintain its technological edge. This is not a question of trade. It is a question of national security."

Q&A: Nvidia H20 and U.S.–China AI Policy

Q: What is the Nvidia H20 chip?
A: The H20 is an AI inference chip designed to run powerful models efficiently. It plays a central role in frontier AI systems.

Q: Why are national security experts concerned?
A: They warn the chip could be used in Chinese military or surveillance applications, and argue that selling it to China undermines U.S. strategic control over AI infrastructure.

Q: What action are the experts calling for?
A: They want the U.S. government to reinstate export restrictions and stop H20 sales to Chinese entities.

Q: What changed in U.S. policy?
A: The Biden administration recently lifted a previous ban on H20 chip exports to China, allowing Nvidia to resume shipments.

Q: What are the broader implications?
A: The case reflects larger tensions between trade policy, national security, and the global AI arms race.

What This Means

The H20 chip controversy exposes a deeper tension at the heart of U.S. AI policy: a clash between short-term economic flexibility and long-term strategic control. The decision to block exports earlier this year sent a clear signal that AI chips like the H20 were too powerful to sell to China. Reversing that ban just months later—particularly in the context of broader trade talks—risks undermining that message.

To national security officials, the inconsistency suggests that export controls may be negotiable, even when the technologies involved have clear military and geopolitical implications. Their letter frames the H20 not as just another product, but as a strategic asset—one that can accelerate frontier AI development in ways that are hard to track and even harder to contain once deployed.

This case also highlights a broader policy gap: while officials publicly emphasize the need for responsible AI development and tech sovereignty, the mechanisms to enforce that vision—such as chip-level export controls—remain vulnerable to external pressure and economic compromise. For now, the question remains unresolved: can the U.S. maintain leadership in critical AI infrastructure while signaling to adversaries that its rules are flexible? Or does that very flexibility weaken the position it seeks to protect?

Either way, the outcome of this debate could reshape how America governs access to its most advanced technologies—and who gets to benefit from them.
