The interaction between might and right is an important topic throughout the development of international relations. Various ideologies and corresponding practices have been put forward by realism, liberalism, constructivism, and international socialism under both Western international relations theories and China’s traditional Wang Dao (王道, “the kingly way” or “benevolent government”), and Ba Dao (霸道, “the hegemonic way” or “rule by force”). In international relations, the rule of law - a phenomenon that has emerged and is continuously developing - is conducive to restraining power politics and promoting right, which is one of the goals of international relations development. China has always opposed hegemony and power politics; it firmly supports a modern system of international law based on the purposes and principles of the UN Charter and aims to build a new international political and economic order with peace, justice, and stability.

The rule of law principle has been established in modern society as a core value in domestic political governance. It evolves from social contract theory and is meant to rein in the almighty and powers from its beginning and later applies to all. In general, international law has become an essential pillar of the present international order. The recent rise of unilateral actions has posed threat to the international rule of law tradition. Equality in international relations, Pacta Sunt Servanda, and good faith implementation of treaty obligations are the essentials of the international rule of law, which provides predictability and stability to the stake holders in the international community. It also represents the fundamental common values of thousands of years of human civilization. Upholding the principle of international rule of law goes to the fundamentals and natures of human beings. Thus, maintaining international rule of law is a guarantee for a better world for all.
