The U.S. has announced measures to block potential sales of advanced AI chips from NVIDIA and AMD to entities owned by Chinese interests abroad, aiming to close a loophole that emerged after the Trump administration discontinued enforcement of Biden-era global chip export restrictions in May 2025. This move is part of a broader effort to revisit and strengthen controls tied to semiconductor exports, reflecting ongoing concerns over national security and the regulation of advanced technology transfers.

AMD: AMD produces high-performance chips used in data centers and AI systems. U.S. officials are moving to block sales of its most advanced AI chips to Chinese-owned entities overseas. The development addresses gaps in earlier global restrictions that were no longer enforced.
NVIDIA: NVIDIA designs and develops advanced graphics processing units and artificial intelligence accelerators central to high-performance computing. The U.S. action targets potential sales of its most advanced AI chips to Chinese-owned entities located abroad. This directly responds to the perceived loophole created after enforcement of prior export rules ended.
Biden administration: The Biden administration established global chip export restrictions during its time in office. Those measures targeted advanced semiconductor technology transfers amid U.S.-China tensions. The current policy change closes a loophole that arose after enforcement of the Biden-era rules was ended.

Trade: Recent actions revisit and strengthen controls previously associated with Biden-era global semiconductor export measures.
Regulation: U.S. policy is actively closing loopholes in restrictions on advanced AI chip exports to foreign entities with Chinese ownership.
