This bill would restrict and monitor investments by Americans in China and related entities in sensitive technology sectors. The Secretary of the Treasury would gain authority to prohibit U.S. persons and companies from making covered investments in Chinese entities working on prohibited technologies—including advanced semiconductors, artificial intelligence, quantum computing, and hypersonic weapons systems. The bill also requires notification of certain investments in notifiable technologies, such as less advanced semiconductors and some AI systems, within 30 days of completion. Violations could result in civil penalties of up to $250,000 or twice the transaction value, and the Secretary could force divestment of prohibited investments. The Treasury Department has 450 days from enactment to issue detailed regulations, which must include opportunities for companies to get non-binding feedback on transactions and self-disclose violations. The Secretary must report annually to Congress for at least seven years on enforcement actions and trends, and must coordinate with allies to develop similar restrictions internationally.
