China is actively seeking in this case to kill any sort of discourse. The UN has no power to impose its values on anyone else. It can, as a body, take certain actions to indirectly affect nations of the world...but it is not a world government that can impose anything.
In this case all that was on the table was a discussion - and even that was untenable to China.
That is China imposing it's values on others in a very absolute way - and I agree...that's an iffy thing. I would go even further and say it's unacceptable (by any country) to try to completely silence discussion.
