Ban on US Talent at China Chip Firms Thwarts Xi’s Key Ambition
Biden administration’s new strictures choke off talent flow
President Xi sees technological advancement as key to future
China will speed its efforts to build a legion of talent and win the battle to develop homegrown technologies, President Xi Jinping pledged at the Communist Party’s twice-a-decade congress on Sunday. But new US restrictions issued a week earlier are already undercutting those plans.
The Biden administration’s latest salvo of sanctions includes restrictions on so-called US persons supporting the development, production or use of integrated circuits at some chip plants located in China. Effective Oct. 12, the measures are broad enough to encompass holders of US green cards as well as US residents and American citizens, capturing a wide swath of senior executives at Chinese semiconductor firms.
“The control on ‘US person’ is the biggest surprise to us from the announcement,” Bernstein analysts including Stacy Rasgon wrote in response to Washington’s move. “Some Chinese companies have been progressing better, often thanks to founding members or executives bringing their experience from years of working in the US. Many of them hence are US citizens or green card holders.”
Anyone falling under the classification will require a license to continue working in China or in support of chipmakers there, with a heavy burden of proof to show that their work wouldn’t go toward military end uses. Given the variety of applications for any given semiconductor, that makes it challenging for US persons to demonstrate they wouldn’t be aiding China’s military, Bernstein said.
