:The U.S. will take steps to prevent American chipmakers from selling products to China that circumvent government restrictions, a U.S. official said, as part of the Biden administration’s upcoming actions to effectively block more AI chip exports.
The new rules, details of which Reuters is reporting for the first time, will be added to sweeping U.S. restrictions on shipments of advanced chips and chipmaking equipment to China unveiled last October. The updates are expected this week, other people familiar with the matter said, though such timetables often slip.
The new rules will block some AI chips that fall just under current technical parameters while demanding companies report shipments of others, said the official, who provided information on condition of anonymity.
A spokesperson for the U.S. Department of Commerce, which oversees export controls, declined to comment.
The latest crackdown on tech exports to China coincides with U.S. efforts to thaw difficult relations between the world’s two largest economies. Several senior members of the Biden administration have met their Chinese counterparts in recent months, and the latest round of rules risks complicating the diplomatic effort.
Last year, government restrictions kept Nvidia, the world’s most valuable chipmaker, from shipping two of its most advanced AI chips to Chinese customers, chips that have become the industry standard for developing chatbots and other AI systems.
But Nvidia soon released new variants for the Chinese market that were less sophisticated and got around the U.S. export controls. One, named the H800, has as much computing power at some settings used in AI work as the company’s more powerful but blocked H100 chip. Still, some key performance aspects are limited, according to a specification sheet seen by Reuters.
The U.S. now plans to introduce new guidelines for AI chips that will restrict certain advanced datacenter AI chips not currently captured, the official said.
While the U.S. official declined to identify which additional chips will be effectively banned, Nvidia’s H800 is a semiconductor sources have suggested the administration has wanted to block.
Chips meant for consumer products like laptops will be exempt from the new curbs, the official said. But companies will need to tell the Commerce Department when they are filling orders for the most powerful consumer chips to make sure they are not being used in ways that threaten national security, according to the official.
The update to the October 2022 rules is also meant to cover AI chips as technology evolves. The U.S. will require companies to notify the government about semiconductors whose performance is just below the guidelines before they are shipped to China, the official said. The government will decide on a case-by-case basis whether they pose a national security risk but can be shipped unless the chipmaker is told otherwise.
The new restrictions may also close a loophole that gives Chinese companies access to American artificial intelligence chips through Chinese units located overseas, as Reuters reported last week.
The rules are not expected to include restrictions on access to U.S. cloud computing services, or those of allies, but will seek comments on the risks of such access and how they might be addressed, the official said.
The Biden administration told Beijing of its plans to update the contentious rules this month, Reuters reported earlier in October, as part of a policy aimed at stabilizing relations between the superpowers.
