U.S. President Joe Biden on Wednesday signed an executive order that will prohibit some new U.S. investment in China in sensitive technologies like computer chips, and require government notification in other technology sectors.
The long-awaited order authorizes the U.S. Treasury secretary to prohibit or restrict U.S. investments in Chinese entities in three sectors: semiconductors and microelectronics, quantum information technologies and certain artificial intelligence systems.
The administration said the restrictions would apply to "narrow subsets" of the three areas but did not give specifics. The proposal is open for public input.
