I understand China prefers to the take as non-interventionist geopolitical position as possible. Personally speaking, I don't agree, but I am also not Chinese nor affiliated with the Chinese government and can't tell them what is best for China. There's the argument to be made that it makes them better mediators for large scale international conflict, and I would certainly prefer China in that position to the US.

I could very well be wrong, and China knows what they are doing better than I do. They've certainly had success in settling international disputes in other arenas, but I don't think the same approach works here. I think the Chinese strategy works brilliantly when you can expect the other country to behave rationally and in their own self-interest, but that isn't the case here.
