Ars Technica · AI60 Experts raise concerns about Nvidia AI chip sales to China and its influence on Trump
China's Ministry of Industry and Information Technology is considering easing restrictions by asking Alibaba and ByteDance to submit plans to buy Nvidia RTX Pro 5500 chips; ByteDance is reportedly planning an order of one million. The report says Jensen Huang has become Trump's most influential adviser on technology issues, and U.S. Treasury Secretary Scott Bessent said Trump and Huang are fully aligned. Some experts worry Nvidia's profit motive is influencing U.S. AI safety policy. Nvidia says these are outdated gaming chips released nearly five years ago and that easing restrictions would only benefit U.S. companies burdened by the limits.
