Firstly - China doesn't have a great human rights record right now. They have an excellent economy.
The earlier communists themselves have one of the worst human rights records.
And you don't "convince" anybody. You let them choose for themselves. Without that part - without being able to choose a bad choice, people can't learn from those mistakes.
You think the west learnt from someone else? People learn from their history and their context.
Remove that from them and well - you remove their ability to have their own identity and history.
Rights can only be understood by the masses after they have examples, leaders, or history which they can translate/relate to.
Thats why India has Gandhi, South Africa has Mandela.
Its very obvious whats happening here, civilization is being brought to the savages.
