“The Wolf Amendment is a law passed by the United States Congress in 2011 that prohibits the United States National Aeronautics and Space Administration (NASA) from using government funds to engage in direct, bilateral cooperation with the Chinese government and China-affiliated organizations from its activities without explicit authorization from the Federal Bureau of Investigation and the U.S. Congress.[1][2][3][4][5] It has been inserted annually into appropriations bills since then.“
