US moves to halt Nvidia AI chip shipments to Chinese firms outside China

The US Commerce Department moved on May 31 to close a loophole that could have allowed advanced Nvidia and AMD AI chips to reach Chinese-owned companies outside China.

The move tightens export controls on high-end semiconductors at a time when Washington is trying to slow China’s access to cutting-edge computing power, and it has drawn criticism from some US senators who say the administration should explain the policy.

US Commerce Department

The department says the guidance is meant to enforce existing export controls and prevent controlled chips from reaching PRC-headquartered companies through overseas subsidiaries. Its position is that licenses are required for shipments of sensitive products and that the rule clarifies, rather than changes, the government’s approach.

Democratic Senators

Elizabeth Warren and Andy Kim argue that the administration may have left a gap that could let advanced American AI chips reach Chinese firms abroad. They are pressing Commerce Secretary Howard Lutnick to testify and explain how the rule is being applied.

Nvidia

Nvidia says its sales and vetting process already matches the government’s existing approach and that it follows licensing requirements for controlled products. The company’s stance is that the guidance confirms what it has been doing rather than introducing a new standard.

  • Nvidia’s chips are used in both cloud data centers and many research labs worldwide.
  • Export controls on semiconductors have become a major tool in US-China technology competition.
  • Subsidiaries abroad can matter because corporate ownership, not location alone, can trigger licensing rules.

US-China Indo-Pacific Rivalry

China and Taiwan coast guard vessels have repeatedly faced off near the Pratas Islands, with the latest standoff showing how small maritime incidents around Taiwan can quickly become confrontations.[1][5] The episode adds to wider U.S.-China military tension across the Indo-Pacific, where Beijing is expanding patrols and Washington is reinforcing regional deterrence.[2][3] The rivalry now centers on preventing miscalculation around Taiwan, the South China Sea, and nearby sea lanes.[1][3][5] It also shapes defense planning by Taiwan, Japan, the Philippines, and the United States as all sides weigh coercion, sovereignty claims, and the risk of escalation.[2][3]
