U.S. To Restrict China’s Access To Cloud Computing Infrastructures

The Biden administration is preparing to restrict Chinese companies' access to U.S. cloud-computing services, according to people familiar with the situation, in a move that could further strain relations between the world’s economic superpowers.

The new rule, if adopted, would likely require U.S. cloud-service providers such as Amazon.com and Microsoft to seek U.S. government permission before they provide cloud-computing services that use advanced artificial intelligence chips to Chinese customers, the people said. The Biden administration’s move on cloud services comes as China said Monday it would impose export restrictions on metals used in advanced chip manufacturing.

This high-stakes conflict over supply-chain access to the world’s most advanced technology is escalating in the days ahead of Treasury Secretary Janet Yellen’s visit to China, a trip the Biden administration hopes will ease tensions. Yellen’s talks in Beijing are expected to touch on macroeconomic conditions in each country, as well as climate change and debt in the developing world.

The U.S.’s proposed cloud restrictions are seen as a means to close a significant loophole. National-security analysts have warned that Chinese AI companies might have bypassed the current export controls rules by using cloud services.

These services allow customers to gain powerful computing capabilities without purchasing advanced equipment—including chips—on the control list, such as the A100 chips by American technology company Nvidia.

China has banned some firms from buying products from Micron Technology, the largest memory-chip maker in the U.S.

“If any Chinese company wanted access to Nvidia A100, they could do that from any cloud service provider. That’s totally legal,” said Emily Weinstein, a research fellow at Georgetown Center for Security and Emerging Technology. The Commerce Department is expected to unveil the action within the coming weeks as part of an expansion of its semiconductor export control policy implemented in October, the people said. The Commerce Department declined to comment.

The ban on cloud services would be the latest in a series of tit-for-tat actions between Washington and Beijing over semiconductors and other advanced technologies. Concerned about China’s advancement in artificial-intelligence technologies and their military applications, the Biden administration is stepping up efforts to limit transfers of chips and other products and services to Chinese companies.

China has struck back, including banning some firms from buying products from Micron Technology, the largest memory-chip maker in the U.S. Yellen has said she is hoping to arrest a downward spiral in relations, as U.S. officials worry that China could cut off access to key goods such as components to electric-vehicle batteries.

In China, meanwhile, officials contend the U.S. is seeking to hobble China’s economic development. Weinstein said that as an alternative to blacklisting certain types of chips in cloud service, the administration could also restrict U.S. cloud companies from offering services to users linked to military, security or intelligence services in China and other countries of concern.

The new policy would expand the reach of the export control policy to a new set of companies beyond the semiconductor and equipment makers. Among U.S. cloud-service providers, Amazon Web Services and Microsoft’s Azure are expected to be the most affected because of their existing presence in the Chinese market.

Neither Microsoft nor Amazon had any immediate comment on the potential action. In October, the Biden administration unveiled restrictions to curb exports of advanced chips and equipment, but hasn’t codified them in final rules.

In the coming weeks, the final and upgraded regulations are expected to be issued, including expanding the scope of restrictions on artificial-intelligence chips made by Nvidia and other chip makers. The new cloud-computing rule will be part of that effort.

As part of the update, the U.S. is also expected to unify the list of controlled chip-making equipment with the Netherlands and Japan. On Friday, the Dutch government published formal rules requiring its companies to seek government permission before they can sell some types of chip-making equipment abroad. 

Under the rule announced by the U.S. last year, U.S. chip makers are required to obtain a license from the Commerce Department to export certain chips used in advanced artificial-intelligence calculations and supercomputing that are used in modern weapons systems. 

Outside of the export control regime, U.S. officials and lawmakers have also been considering implementing steps to curb U.S. operations of Chinese cloud-service providers such as Alibaba and Tencent.
