China is too smart and cautious to get itself involved in such a conflict. They gave their token support to Serbia and that’s it - nobody in the CPC wants China to be seen as the one stirring up conflict in Europe or elsewhere.

Same reason why they don’t (openly) support the NPA in the Philippines and they keep reiterating that they want a peaceful solution to the SMO. China cares about being seen as the reasonable mediator, someone countries can rely on to actually stop conflicts instead of escalating them like SOME countries do
