China’s space officials said Thursday they welcomed scientists from across the world to apply to study the lunar rock samples the Chang’e 6 probe brought back to Earth in a historic mission, but noted there were limits to that cooperation, specifically with the U.S.
The Wolf Amendment was enacted in 2011 and prevents direct U.S.-Chinese bilateral cooperation except in cases where the FBI can certify that there is no national security risk to sharing information with the Chinese side in the course of work.

Still, as good as American scientists may be, i can trust scientists from a reputable proxy. I believe that the us has reasons to be cagey with China, and this really was just a pointless dig and a showing of frustration that may or may not be related to dark side moon rock composition.
