You seem to be misunderstanding the usage of the word "expectation" in this context. I want China to meet a higher standard of behavior. China is failing to meet that standard.

Sure, we all wish humanity would "do better".

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.

I have high expectations for a child even if that child hasn't demonstrated better before. Again, you're simply misunderstanding the usage of the word "expectation". That I "expect" better from them means they need to do better, not that they will.
