Washington, Oct 28 (Reuters) - The Biden administration announced on Monday that it is finalizing regulations aimed at restricting U.S. investments in China’s artificial intelligence and other high-tech sectors that may pose risks to U.S. national security. These rules, initially proposed by the U.S. Treasury in June, follow an executive order signed by President Joe Biden in August 2023. The restrictions target three critical areas: semiconductors and microelectronics, quantum information technologies, and specific AI systems.
