The U.S. Department of the Treasury has released final regulations aimed at implementing an executive order that restricts investments in certain national security technologies and products, particularly in countries deemed a threat to the United States, such as China. This announcement follows the issuance of final regulations concerning the Section 45X advanced manufacturing production credit, which aims to incentivize domestic manufacturing. Additionally, the IRS has finalized regulations regarding syndicated conservation easement transactions, further impacting tax law and environmental policy. These developments reflect ongoing efforts by the U.S. government to address national security concerns and promote advanced manufacturing within the country.
