Working together on commercial space technology is good. But space technology also has military uses, in which case both China and the US have strategic reasons for being competitive. Example: a few years ago China decommissioned one of its weather satellites by firing a rocket at it from Earth. Some speculated this new technology could be used to wipe out the USA's anti-nuclear system, leaving it vulnerable to an attack.
