# Wolf Amendment The Wolf Amendment is a rule in federal spending law that bars [[NASA]] from using its money to work directly with [[China]] or Chinese-owned companies. It was first enacted on 15 April 2011, as Section 1340 of that year's full-year spending law, and Congress has written it into the annual appropriations bill that funds NASA every year since. It is the main legal reason China is not a partner on the [[International Space Station]], and why the world's two largest space programs barely talk to each other. ## What it says The rule blocks NASA and the White House Office of Science and Technology Policy from spending money to plan or carry out *bilateral* programs, contracts or coordination with China or Chinese-owned companies, and from hosting official Chinese visitors at NASA facilities. It is not a total ban. An activity can go ahead if Congress specifically authorizes it later, or if NASA certifies to Congress in advance that it poses no risk of handing China sensitive technology or data and does not involve officials connected to human-rights abuses. Because it is a spending rule, not a standalone law, it has to be renewed every year. Both parties have renewed it every time. ## The man behind it The amendment is named for Rep. Frank Wolf, a Virginia Republican who served in Congress from 1981 to 2015 and, in 2011, chaired the House subcommittee that wrote NASA's budget. Wolf was best known as a human-rights advocate who had long criticized Beijing, including over the [[Tiananmen Square Massacre]]. His case for the amendment combined two concerns: Chinese espionage against American technology, and the moral problem of partnering with a government that abuses its own people. ## How it has worked in practice - **2013: the Kepler conference.** NASA's Ames Research Center barred Chinese nationals from a scientific conference on the Kepler space telescope. American scientists boycotted in protest. Wolf himself wrote to NASA saying the law covered only bilateral government cooperation, not individual scientists at an international meeting, and NASA reversed the ban. - **2019: Chang'e 4.** NASA used the certification process to coordinate with China when China landed on the far side of the Moon, so a NASA lunar orbiter could observe the landing. - **2023–2025: Moon samples.** China offered samples from its Chang'e 5 mission to researchers worldwide. In late 2023, NASA allowed researchers it funds to apply. But when a Stony Brook University scientist was later selected to receive samples, NASA said it would not fund his study of them, citing the amendment. China has made the same offer for far-side samples from Chang'e 6 and has pointed to the U.S. law as the obstacle. - **2026: tighter enforcement.** On 14 May 2026, the [[House Select Committee on the Chinese Communist Party]] published a report on how NASA enforces the rule. It found that NASA does little checking after it awards grants, called universities' safeguards "largely performative," and flagged NASA-funded papers whose only co-authors were affiliated with Chinese institutions as potential compliance concerns. Among its ten recommendations were a NASA inspector general–Justice Department task force on violations and debarment for repeat offenders. ## The argument over it **Supporters** say the amendment has kept American space technology out of the hands of a military rival. China's space program is closely tied to its military, so in their view almost any cooperation risks helping the People's Liberation Army. **Critics** say it backfired. Shut out of the space station and American partnerships, China built its own station, Tiangong, its own navigation system and its own Moon program, and now offers partnerships to other countries on its own terms. Critics also argue that having almost no working channel between the two biggest space powers makes accidents and misunderstandings in orbit more dangerous, especially as debris and crowded orbits become a shared problem. ## Why it's on the map The Wolf Amendment is one of the longest-running technology-denial policies aimed at China, and it predates the semiconductor and AI export controls that dominate today's debate. Fifteen years in, it offers evidence for both sides. It probably did limit China's direct access to NASA technology. It also coincided with China building Tiangong, the only permanently crewed space station outside the partnership that runs the International Space Station. The same tradeoff is now being argued over chips and AI, and the [[Chinese Space Program Hub]] makes the case that space is the precedent. ## See also - [[Chinese Space Program Hub]] — what China built after being shut out - [[NASA]] — the agency the rule restricts - [[House Select Committee on the Chinese Communist Party]] — the 2026 enforcement report - [[China Initiative]] — the Justice Department's 2018–2022 campaign against Chinese research espionage - [[Long March Rockets]] — and the 1996 crash that began the U.S.-China space split - [[International Space Station]] — the partnership China is excluded from
