Last August U.S. lawmakers passed the National Defense Authorization Act which was designed in part to stem Chinese acquisitions of strategic technology by requiring more stringent reviews of investments; in 2018 Chinese venture capital investments in U.S. startups reached $3.3 billion, a new record; the new rules have not been fully implemented yet so investment dollars could reduce once that happens; the new law means that more proposed investments by foreigners in technology companies must be submitted for review to the Committee on Foreign Investment.
