From the Document: "On February 14, 2019, the European Parliament approved a regulation (an EU law) that establishes a cooperation mechanism for screening foreign direct investment (FDI) in EU members that focuses on foreign investment in 'critical technologies.' This action follows those of other jurisdictions, including the United States through enactment of the Foreign Investment Risk Review Modernization Act of 2018 (FIRRMA) that enhanced the role of the Committee on Foreign Investment in the United States (CFIUS), to increase scrutiny of FDI as a component of national security. The legislation was approved by the EU members on March 5, 2019; this will be followed by an 18-month implementation period."
