NASA has banned Chinese citizens from working on its space programs for security reasons.

NASA has begun to prohibit Chinese citizens, including those with valid visas, from participating in its programs, a measure confirmed by the government agency. This policy change was prompted by the escalation of anti-China rhetoric under the Trump administration. Chinese citizens, who previously could work as students or contractors, have been excluded from IT systems and face-to-face meetings. In the context of the competition for lunar exploration, NASA emphasizes that America will remain a leader in the space field.
