The U.S. reportedly announced new restrictions on exports of advanced chips to China, including two made-for-China chips from Nvidia.
U.S. chip stocks fell as the curbs also hit Advanced Micro Devices and Intel.
Loopholes
The curbs are aimed at closing loopholes that became apparent after the U.S. announced export curbs on microchips in October 2022. The restrictions are designed to prevent China’s military from importing advanced semiconductors or equipment.
Nvidia has said in a filing that the new export restrictions will block sales of two high-end artificial intelligence chips it created for the Chinese market – A800 and H800. It said that one of its gaming chips will also be blocked.

Although the curbs also affect other chip makers, analysts believe Nvidia will be hit the hardest because China accounts for up to 25% of its revenues from data centre chip sales. Nvidia’s shares, which are considered a star stock, fell by as much as 4.7% in the wake of the announcement.
Semiconductor Industry Association
The Semiconductor Industry Association, which represents 99% of the U.S. semiconductor industry by revenue, said in a statement that the new measures are ‘overly broad‘ and ‘risk harming the U.S. semiconductor structure without advancing national security as they encourage overseas customers to source elsewhere’.
China reacts
A spokesperson for the Chinese embassy also said that it ‘firmly opposes‘ the new restrictions, which also target Iran and Russia and go into effect in 30 days.
Two months ago, China retaliated by restricting exports of two materials, gallium and germanium, which are key to the semiconductor industry.
The materials are ‘minor metals‘, meaning that they are not usually found on their own in nature, and are often the by-product of other processes. It’s not only the U.S., Japan and the Netherlands – which is home to key chip equipment maker ASML – have also imposed chip technology export restrictions on China.
Fallout
The constant ‘fall-out’ between the world’s two biggest economies has raised concerns over the rise of so-called ‘resource nationalism‘ – a practice where governments hoard critical materials to exert influence over other countries.
