Chinese exclusion policy of NASA

The Chinese Exclusion Policy of NASA (National Aeronautics and Space Administration) was a set of rules that said that people from China were not allowed to work at NASA. This rule was in place from the early 1960s until the late 1990s. It meant that people from China were not allowed to do certain jobs and sometimes even go to certain places at NASA. This was because some people thought that people from China might not be able to do the job or might be a threat to US citizens or government secrets.
