Chinese should get off this public image of constantly asking for cooperation & collaboration. They should publicly embrace the competition with the West and slogan it up. The Global South respects strength above all.There used to be a belief that once China displays more of their advances and express willingness to do big projects like James Webb they will be collaboration. That's not true at all. Further advances in Chinese space technology will further this tension, not increase the likelihood of cooperation.
Wolf has been supported by every Adminstration since 2011 (Bill Nelson just recently voted to keep the Wolf Amendments). You can cite human rights or IP concerns but the truth is while there are some scientists in NASA and other US colleges that want partnerships with China in certain areas such as astronomy, from a couple of my old jobs I can confirm the overwhelming majority of people there and subcontractors that support them do not want any collaboration and they absolute see it as a space race.
No Chinese astronauts has ever visited the ISS and I have no doubt that this will extend towards projects on the lunar surface in the 2030s.
