James Jackson has prepared a six page primer on U.S. national security vetting of foreign investments (Foreign Investment, CFIUS, and Homeland Security: An Overview, Congressional Research Service, April 17, 2008).
Jackson develops an argument that last year's Congressional action to revise the process, the Foreign Investment and National Security Act (FINSA), is meant to address threats to something called "national economic security." He does so by ignoring the language of FINSA, and introducing language from a separate statute.
June 14: Since I wrote this, I've found that, while FINSA doesn't include a definition of "national security," or "national economic security" it does include a "clarification" among its definitions stating "The term `national security' shall be construed so as to include those
issues relating to `homeland security', including its application to
critical infrastructure." I'm not sure what this means, but I'm not as certain as I once was that the language of FINSA precludes something its proponents call "national economic security." See the text added to the end of this post.
"Economic security" is a problematic concept. Summarizing a discussion in Graham and Marchick (US National Security and Foreign Direct Investment), a national economic security test might create a general foreign investment review process that would inhibit foreign investments in the U.S.and provide other countries with an excuse to subject U.S.investments to similar review. It would be hard to enforce because it's extremely hard to define what “economic security” means. It would provide endless opportunities for companies to suppress competition by making spurious claims that a foreign investment in a competitor violates some "economic security" test. It would encourage politicization of the review process.
A quick word search of the final text of the bill (FINSA) shows that it does not use the term "'economic security." FINSA does include references to "critical infrastructure," and Jackson suggests that a concern with economic security can be introduced into this bill by using the definition of critical infrastructure from another piece of legislation (to anticipate the argument at the end of the post - FINSA uses a different definition of critical infrastruture than the legislation Jackson cites):
