This bill, known as the "No Safe Harbor for the Enemy Act," proposes an amendment to the William M. (Mac) Thornberry National Defense Authorization Act for Fiscal Year 2021. Its primary purpose is to modify the existing provisions concerning the public reporting of Chinese military companies operating within the United States. The key change involves inserting a new subsection into Section 1260H of the original Act. This new provision stipulates that any decision made by the Secretary of Defense regarding the addition of an entity to the list of Chinese military companies shall be considered final and conclusive . Furthermore, such decisions will not be subject to review by any other official or by any court, including through actions like mandamus.
