Xi Jinping always reflects on Chinese diplomatic work from the perspective of dialectical unification of theory of two-point and key-point. On the one hand, he emphasizes that China should catch the key point and actively construct new international relationship among major countries; on the other hand, he always stresses that China should make overall plans and take all fctors into consideration and advance the work of multilateral diplomacy and neighboring diplomacy among developing countries. These strategies fully embody his dialectical thinking and the method of the concrete analysis of concrete problems.
