The Russia-Ukraine conflict is not only a geopolitical rivalry between Russia and the U.S.-led West,but also a rivalry between the two sides around the international order.After the collapse of the Soviet Union,the U.S.hegemonic order expanded rapidly across the globe and attempted to form a geopolitical structure,an economic division of labor,and a corresponding rule of values dominated by the U.S.,thereby anchoring other countries in a peripheral zone of mutual checks and balances.Reflections on the liberal reforms of the 1990s and revitalization efforts since the new century have led to increasingly sharp contradictions between Russia and the U.S.hegemonic order,mainly in the form of a conflict of interests over economic development,a geopolitical conflict over the competition for power,and a conflict of perceptions over the norms of the order.In the face of the strategic superiority and collective rejection of the United States and the West,Russia's need to push for a change in the international order has become more urgent.To this end,Russia has taken the criticism of the shortcomings and hypocrisy of the United States'hegemonic order as its strategic focus,and is actively promoting its vision of a multipolar world order,drawing on the security concerns of the countries of the Global South and the need for autonomous development.And out of the need to maintain its own hegemony,the U.S.is also accelerating the adjustment of its foreign policy of the liberal international order,regaining its ideology and camp confrontation,and attempting to form an orderly containment of forces such as China and Russia.Whatever the final outcome of the Russian-Ukrainian conflict,it will exacerbate the complexity of the changes in the international order and the acrimony of the struggle in the future.Of course,the competition between the United States and the Western world and Russia over the international order will objectively provide a new historical opportunity for the global South to build a fairer and more reasonable new international order,and in the long run will help to bring all parties back to the purposes and principles of the Charter of the United Nations and international law.
