Russia is very similar to the rest of western democracies, so I won't comment further on that.
Regarding China, their leading party hasn't switched in 80 years, but their policies have and have plenty actually. Changing parties matters only a little bit in the grand scheme of things. I'd argue, for example, that Japan, that has been ruled by a single party for all of his modern existence, is still considered by many in the west as a functioning democracy.
In any case, I think all the replies have made my point for me that your dismissal of our rhetoric as based on "western arrogance" are simply nonsense. It's in fact you who's displayed a lack of understanding of those you argue against.
