BEIJING: A Chinese university with deep ties to the People’s Liberation Army (PLA)bought Nvidia’s powerful H200 AI chips last month despite being on a US export blacklist, procurement records show, highlighting gaps in Washington’s efforts to curb China’s access to advanced technology.

The findings come as Nvidia and its CEO Jensen Huang face mounting scrutiny in Washington over his lobbying for looser restrictions on sales of AI chips to China, following reports alleging he was targeted by a Chinese spying operation.

Huang has argued that continued US sales to China would preserve American ​technological leadership and keep Chinese customers reliant on US technology. But some US lawmakers say access to Nvidia’s most powerful AI chips can speed China’s development of AI systems for weapons design, intelligence analysis and military modernisation.
