This month, Congress is debating the latest version of the National Defense Authorization Act. One of the most difficult defense issues on the table has nothing to do with new weapons systems, force structure or personnel. The bill includes a plan for changing the interagency process for vetting foreign investment and reforms to the Committee for Foreign Investment in the United States (CFIUS). CFIUS reviews and can stop foreign investment in what are deemed to be critical industries to national security. CFIUS has come under increasing scrutiny as China has invested heavily in the U.S. tech sector and many fear are attempting to buy or steal the crown jewels of U.S. technology.
