But if your baseline expectations are low, you are rarely disappointed. For an organization or individual to have its expectations changed from "low" to "high", there should be some basis for such an upgrade, primarily actions taken by the organization that demonstrate higher performance (for whatever metric you are using to define "performance", in this case protection of human rights).

Does the Chinese Communist Party have a demonstrable history of embracing or advancing human rights? IMO, no. So they remain at the "low expectations" baseline.
