The United States Congress is intensifying efforts to curb the export of advanced artificial intelligence chips to China, casting fresh uncertainty over Nvidia's access to the Chinese market. Republican lawmakers are seeking to attach AI chip export restrictions to the annual defense bill, a Senate aide confirmed, a move that could severely disrupt shipments to China.

Congressional push for tighter restrictions

According to a Senate aide cited by The Daily Star, Republican members are pushing to include provisions in the annual National Defense Authorization Act (NDAA) that would impose new limits on AI chip exports. If enacted, the measure would effectively bar Nvidia's most advanced chips from entering the Chinese market. The Biden administration has already imposed strict controls on some high-performance chip exports to China, but the congressional initiative would codify and expand those restrictions into law.

Blacklisted university acquires H200 chips

The legislative push gains urgency amid revelations that a Chinese university with close ties to the People's Liberation Army purchased Nvidia's powerful H200 AI chips last month, despite being on the US export blacklist. The transaction has raised serious questions about the effectiveness of existing sanctions and has strengthened the hand of lawmakers demanding tougher enforcement measures.

Implications for the chip industry

The H200 is among the world's most advanced AI training chips, and China's technology sector relies heavily on such hardware for research and development. A congressional ban would deliver a significant blow to China's AI ambitions while also posing economic challenges for US companies like Nvidia, which view China as a critical market.

Next steps

The proposed restrictions must clear both the Senate and the House of Representatives as part of the defense bill. Political analysts suggest the measure stands a strong chance of passage given the intensifying US-China technological rivalry. However, its enactment could further escalate tensions between Washington and Beijing, with potential repercussions for global supply chains and diplomatic relations.
