Tech war: US eyes more AI chip curbs on Chinese companies abroad to close loophole
- US rules restricting shipments of AI chips and chipmaking tools to China are set to be tightened in the coming days, sources say
- In the initial round of curbs, the Biden administration left overseas subsidiaries of Chinese companies with unfettered access to the AI chips
In the initial round of curbs, the Biden administration left overseas subsidiaries of Chinese companies with unfettered access to the same semiconductors, meaning they could easily be smuggled into China or accessed remotely by China-based users.
Washington is now mulling ways to close the loophole, sources said, a move that has not been previously reported.
The efforts to close the loophole show how the Biden administration is struggling to cut China off from top AI technology and how difficult it is to plug every gap in export controls.
“Absolutely, Chinese firms are purchasing chips for use in data centres abroad,” said Greg Allen, a director at the Center for Strategic and International Studies, noting that Singapore is a big hub for cloud computing.
The Commerce Department declined to comment. A representative from the Chinese embassy in Washington did not immediately respond to a request for comment. China’s Ministry of Commerce has previously accused the US of abusing export controls and called for it to “stop its unreasonable suppression of Chinese companies”.
While it would be illegal under US law to ship those AI chips to mainland China, it is very difficult for the United States to police those transactions, experts said, noting that China-based employees could legally access the chips located at foreign subsidiaries remotely as well.
“We don’t actually know how big a problem this is,” said Hanna Dohmen, a research analyst at Georgetown University’s Centre for Security and Emerging Technology (CSET).
The United States has been seeking to halt the rise of China’s artificial intelligence capability, which helps its military develop unmanned combat systems, according to a report in The International Affairs Review, affiliated with George Washington University’s School of International Affairs.
Washington has been working to close other loopholes that allow the AI chips into China. In August, it told Nvidia and AMD to restrict shipments of the AI chips beyond China to other regions, including some countries in the Middle East.
Sources said the new rules on AI chips expected this month are likely to apply those same restrictions more broadly to all companies in the market.
It is less clear how the US government might close the loophole allowing Chinese parties to access US cloud providers like Amazon Web Services, which give their customers access to the same AI capabilities. But sources say the Biden administration is grappling with that issue as well.
“Chinese persons can completely legally access the same chips from anywhere in the world. There are no rules about how they can be accessed,” said Timothy Fist, a fellow at Washington-based think tank Centre for a New American Security.
