This proposed legislation seeks to amend Section 1260H of the William M. (Mac) Thornberry National Defense Authorization Act for Fiscal Year 2021. Its primary purpose is to clarify the administrative treatment of determinations made by the Secretary of Defense regarding the identification of Chinese military companies. Specifically, the bill stipulates that such determinations shall be considered a military or foreign affairs function for purposes of section 554 of title 5, United States Code. This designation means that these actions are explicitly not subject to the various provisions of the Administrative Procedure Act, including sections 551, 553 through 559, and 701 through 706, thereby streamlining the process and reducing administrative oversight for these specific national security decisions.
