When it is viewed as hostile to even ask the question of whether human rights are an issue, it’s pretty obvious that there are problems being hidden from view.
China (or rather, Chinese authorities in general) would not accept to have the type of access that would enable to rule out human rights abuses, and there is no reason to believe that media freedoms are sufficient to just trust whatever perspective is published.
Possibly, some apparatus could be established to develop mutual reinforcement of human rights values, potentially with some similar (by which I mean bi-directional) degree of empowerment in protection of whatever these declared values pertaining to rights might be.
I do believe there have been some efforts to both constrain and actively deter the extent of organ harvesting from prisoners, among other things to prevent the existence of a profit incentive for prisoner deaths. Such revelations are in the present context more reassuring of things going in a better direction, than the observation of a presently-high level of worldwide censorship of basically all pro-rights heads of state against suggesting (beyond lip service for domestic audiences) that these and other human rights issues should be addressed.
