From the Document: "The Committee on Foreign Investment in the United States (CFIUS) is an interagency body comprised of nine Cabinet members, two ex officio members, and other members as appointed by the President, that assists the President in reviewing the national security aspects of foreign direct investment in the U.S. economy. While the group often operated in relative obscurity, the perceived change in the nation's national security and economic concerns following the September 11, 2001, terrorist attacks and the proposed acquisition of commercial operations at six U.S. ports by Dubai Ports World in 2006 placed CFIUS's review procedures under intense scrutiny by Members of Congress and the public. In 2018, prompted by concerns over Chinese and other foreign investment in U.S. companies with advanced technology, Members of Congress and the Trump Administration enacted the Foreign Investment Risk Review Modernization Act of 2018 (FIRRMA), which became effective on November 11, 2018. This measure marked the most comprehensive revision of the foreign investment review process under CFIUS since the previous revision in 2007, the Foreign Investment and National Security Act (FINSA)."
