Washington restricts Nvidia’s AI chip shipments over national security concerns, as pressure builds in ongoing US-China tech and tariff disputes.
Taipei, April 16: The United States has imposed new restrictions on the export of Nvidia’s H20 AI chips to China, intensifying efforts to curb Beijing’s access to cutting-edge artificial intelligence hardware amid growing geopolitical and trade tensions, Radio Free Asia (RFA) reported.
Nvidia revealed on Tuesday that it was notified by the US government on April 9 that the shipment of its H20 chips to Chinese clients would now require official government approval, with no expiration date on the restriction.
Though the H20 is not Nvidia’s most advanced chip, its high-bandwidth memory and optimized architecture make it a powerful tool for high-performance computing systems. The US reportedly cited concerns that the chip could be adapted for use in Chinese supercomputers, which are often tied to national security and military projects.
The H20 was previously the most advanced AI chip legally permitted for sale in China, after the US began restricting sales of higher-end semiconductors under its October 2022 export control framework. While it lags behind Nvidia’s new Blackwell chip, its affordability and computing potential had drawn interest from major Chinese tech players.
In January, Chinese AI startup DeepSeek used the H20 chip to launch a cost-effective AI model that gained global attention. Reports also suggest that tech giants including Alibaba, Tencent, and ByteDance placed combined orders exceeding $16 billion for H20 chips in Q1 2025—a 40% increase from the previous quarter.
The timing of the restriction aligns with rising US-China trade friction, especially after Washington announced reciprocal tariffs and paused certain trade deals earlier this month. These chip-related sanctions reflect a broader strategy by the US to limit China’s technological rise, particularly in fields like AI and quantum computing.
As of now, US authorities have not publicly commented on whether the restriction might extend to other mid-range chips in the future.
