In order to avoid a situation where US investors do not have reciprocal abilities to invest in foreign airlines, the United States should not liberalize its ownership laws with respect to foreigners from countries whose governments own any portion of their national airlines, including indirect ownership through a sovereign wealth fund.226 The United States should also prohibit foreigners who are from countries that maintain strict ownership and control laws from investing in US carriers to ensure that foreigners do not gain unequal access to the US aviation market.227 Finally, the United States should set up a system to review potential foreign investors looking to make significant investments in US air carriers. Any investor deemed to be less than friendly to US interests would not be permitted to invest in US carriers. Additionally, in the event of a liberalization of aviation foreign investment laws, the President would retain his authority under the Exon-Florio
Amendment to block any mergers, acquisitions, or takeovers of US air carriers that he believes would threaten US national security interests.
