Chinese exclusion policy of NASA
Keine Chinesen in der NASA!
Due to security concerns and various other motivations, US government prohibits all researchers from the U.S. National Aeronautics and Space Administration (NASA) from working bilaterally with Chinese citizens affiliated with a Chinese state enterprise or entity. In April 2011, the 112th United States Congress banned NASA from using its funds to host Chinese visitors at NASA facilities. In October 2013, NASA reversed the previous ban on working with Chinese scientists, so long as they did not represent their government in any official capacity
