In an escalating move against foreign chipmakers, Chinese regulators have taken aim at Nvidia’s H20, the most advanced AI chip the U.S. company is currently permitted to sell in China. According to Bloomberg, Chinese authorities have instructed major local tech giants, including Alibaba, ByteDance, and Tencent, to suspend any purchases of the H20 chip, particularly for projects linked to government or national security activities.

Chinese Authorities Urge Companies to Avoid H20 Chip Usage in Sensitive Sectors

The Chinese government has raised concerns about potential security risks tied to U.S. technology, specifically calling on local tech firms to avoid using Nvidia’s H20 chip in government-related or security-sensitive work. The warning highlights Beijing’s growing caution about relying on foreign chips in critical sectors. Sources report that several companies, including the likes of Alibaba and Tencent, have received formal notices advising against using the H20 chip in sensitive private-sector or government projects.

Nvidia’s H20 processor, which was initially subject to restrictions due to U.S. sanctions, was recently permitted for sale to China after a partial easing of export controls. However, China’s increasing apprehension regarding its use in state-affiliated projects now threatens Nvidia’s ability to capitalize on this market. The company is already grappling with billions in lost revenue from its China business, making this additional setback particularly damaging.

Nvidia Responds: No Military Use or Security Risks

In defense of its technology, Nvidia has reiterated that its H20 chip is “not a military product nor designed for government infrastructure.” The chipmaker has stressed that China has ample access to domestically produced chips that meet its government needs, pointing out that, like the U.S., China does not depend on foreign chips for its own government operations. Nvidia also asserted that its products are secure, denying claims that the H20 chip contains any “backdoors” for unauthorized remote access or control.

Despite these assurances, China’s Ministry of Industry and Information Technology (MIIT) is reportedly questioning major firms about their orders for the H20 chip, urging them to explore local alternatives. Several companies are reportedly reconsidering or scaling back their purchases. Furthermore, China’s Cyberspace Administration has ordered more than a dozen companies, including Tencent, to pause H20 chip purchases until investigations into potential security risks are concluded.

The Timing and Implications of the Ban

This development comes in the wake of mounting geopolitical tensions over advanced AI technology. In May, the U.S. proposed legislation requiring chipmakers, including Nvidia, to verify the final destination of AI chips sold abroad, particularly in China. This proposal is part of broader U.S. efforts to limit China’s access to cutting-edge technologies that could bolster its AI and military capabilities.

The latest actions from China reflect its broader ambition to replace foreign technologies with domestic alternatives, including AI chips from Huawei, which are increasingly seen as key to Beijing’s self-sufficiency in the semiconductor space. These efforts have already seen a boost in local chipmakers like SMIC (Semiconductor Manufacturing International Corporation), whose shares rose 5% on expectations of growing demand for domestic chips.

U.S. Response and Nvidia’s Future in China

Amid these tensions, U.S. officials have proposed allowing Nvidia to sell a scaled-back version of its Blackwell chip in China, even as Washington remains wary of the implications for China’s military. Additionally, the Biden administration recently struck a deal requiring Nvidia and AMD to remit 15% of their revenue from sales of advanced chips in China to the U.S. government, a move designed to ensure that these technologies do not inadvertently bolster Beijing’s military capabilities.

Nvidia’s future in China remains uncertain, with the company’s ability to navigate these shifting regulatory landscapes playing a pivotal role in determining whether it can continue to profit from one of the world’s largest tech markets.

Industry Reactions and the Path Forward

While major players like Alibaba, ByteDance, and Tencent have not commented publicly on the latest developments, the impact on Nvidia’s sales and the broader semiconductor market in China could be significant. The ongoing push for local alternatives, coupled with increasing scrutiny of foreign technology, signals a pivotal moment in the race for dominance in global AI and semiconductor markets.

As China accelerates its efforts to replace foreign tech, the global semiconductor landscape is being reshaped, with a growing emphasis on self-sufficiency and national security. The outcome of this standoff between China and the U.S. will likely have profound implications for the future of AI technology and the global supply chain
