The US Treasury Department has announced that it is finalizing rules to restrict US investments in Chinese technologies that could potentially threaten American national security, as directed by a Biden administration order. The new rules will cover the semiconductor microelectronics, quantum information technologies, and certain artificial intelligence systems. According to Treasury officials, the rules will also cover 'advanced cryptography-breaking computer systems or next-generation fighter jets' and will be enforced by the newly established Office of Foreign Assets Control beginning January 2nd. The move comes as the US government seeks to limit China's access to advanced technologies that could be used to harm national security interests. The restrictions are part of a broader effort to regulate China's growing influence in the tech industry and to protect American intellectual property and trade secrets. The rules are likely to be opposed by some US companies that have significant investments in China, but proponents argue that they are necessary to protect national security and promote American economic interests.
