The Wolf Amendment is a law passed by the United States Congress in 2011, named after then–United States Representative Frank Wolf, 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.

In May 1999, the?Report of the Select Committee on U.S. National Security and Military/Commercial Concerns with the People's Republic of China?was made public. It alleged that technical information provided by American commercial satellite manufacturers to China in connection with satellite launches could have been used to improve Chinese intercontinental ballistic missile technology.?

In 2010, Rep.?John Culberson?urged President?Barack Obama?not to allow further contact between NASA and the?China National Space Administration?(CNSA). In a letter addressed to the President, he wrote:?

I have grave concerns about the nature and goals of?China’s space program?and strongly oppose any cooperation between?NASA?and?CNSA’s human space flight programs without?Congressional?authorization.[6][7]?

In April 2011, the?112th United States Congress?banned NASA from engaging in bilateral agreements and coordination with China.[1]?As stated under Public Law 112–10, Sec. 1340:?

(a) None of the funds made available by this division may be used for the National Aeronautics and Space Administration or the Office of Science and Technology Policy to develop, design, plan, promulgate, implement, or execute a bilateral policy, program, order, or contract of any kind to participate, collaborate, or coordinate bilaterally in any way with China or any Chinese-owned company unless such activities are specifically authorized by a law enacted after the date of enactment of this division. (b) The limitation in subsection (a) shall also apply to any funds used to effectuate the hosting of official Chinese visitors at facilities belonging to or utilized by the National Aeronautics and Space Administration.[1]?

In 2013, officials at NASA Ames prohibited Chinese nationals from attending?Kepler Science Conference?II. A number of American scientists boycotted the meeting, with senior academics either withdrawing individually or pulling out their entire research groups.[8]?Rep.?Frank Wolf?wrote a letter to NASA Administrator?Charlie Bolden, saying that the restriction only applied to bilateral meetings and activities between NASA and the Chinese government or Chinese-owned companies, whereas Kepler Science Conference II is a multilateral event.[9]?NASA later reversed the ban and admitted a mistake in barring individual Chinese nationals who did not represent their government in official capacity.[10]?

During China's 2019?Chang'e 4?mission, NASA collaborated with China to monitor the moon lander and Yutu 2 rover on the lunar far-side using NASA's?Lunar Reconnaissance Orbiter. NASA was able to do so by getting congressional approval for the specific interaction and sharing data with researchers globally.[11]?NASA stated:?

The statutory prohibition on NASA’s use of appropriated funds for bilateral cooperation with China…does not apply to activities that NASA has certified to Congress, [which] do not pose a risk of resulting in the transfer of technology, data or other information with national security or economic security implications to China; and that do not involve knowing interactions with officials who have been determined by the U.S. to have direct involvement with violations of human rights. In accordance with the law, NASA made the appropriate certification to Congress for this activity.[11]
