evidence: China’s ability to buy US land near military bases just got more restricted [...] In September 2012, for instance, then President Barack Obama used CFIUS authorities to issue a divestment order against a Chinese company that had invested in a wind farm near a US naval base in Oregon used for weapons testing and training. CFIUS was able to intervene because the Chinese company had invested in a US business. This case helped to make these kinds of collocational risks clear to US lawmakers, but before FIRRMA, there were no federal government authorities to block the sale or lease of land to foreign nationals near sensitive government sites. FIRRMA closed that regulatory gap. [...] This is the second time that the list of sensitive sites has been updated. The first update was made in August 2023 after a controversial proposed greenfield investment by a Chinese firm of North Dakota farmland located about twelve miles from a military site was found to be outside the scope of CFIUS’s original jurisdiction. The newly proposed rules come shortly after the Biden administration issued an executive order in May requiring a Chinese firm to divest its holdings in a crypto mining operation in Wyoming located within a mile of Warren Air Force Base. This was the first use of CFIUS’s real estate authorities to formally block a transaction that was structured as a real estate purchase and subsequent greenfield investment.
