The U.S. Treasury Department released two final regulations expanding the government's oversight of certain foreign investments into the country in a bid to better address national security risks.

The regulations, which take effect Feb. 13, grant the Committee on Foreign Investment in the U.S., or CFIUS, wider authority to assess foreign noncontrolling investments into certain U.S. businesses involved in critical technology, critical infrastructure, or sensitive personal data. Covered investments that involve critical U.S. infrastructure include those in telecommunications, certain metal resources, LNG and oil pipelines.

The rules also allow the CFIUS to review certain real estate transactions by foreign persons in areas with or surrounding airports, maritime ports and military installations.

The Treasury proposed the reforms in September 2019. Australia, Canada and the U.K. are exempt from the tighter regulations, the department said, adding that it may expand the list of exceptions in the future.
