数百年来的历史证明了这样一个道理：每一段国际关系的形成，每一个国际体系的建立，都带有鲜明的时代印记，也必须随着时代发展不断创新完善，否则就会跟不上时代脚步，甚至会失去它的先进性和合理性。

What has happened over the centuries has proved one thing. The development of international relations, and the forming of the international system, at each period, bears a unique mark of the time. We all need to move on and keep abreast of the times to make the international relations and international system of our times effective and relevant to the world we live in.

70年前，在世界反法西斯战争胜利的硝烟中，各国携手创建了以联合国为核心、以《联合国宪章》的宗旨原则为基础的国际秩序和相应国际体系，这是人类文明的又一次巨大进步，为国际关系和国际体系建设翻了新的历史篇章。

70 years ago, in the wake of victory of the world’s anti-fascist war, nations on earth created an international order and a corresponding international system with the United Nations as the core underpinned by the purposes and principles of the UN Charter. What it marked was a giant step forward in the history of human civilization, a proud new chapter in the evolution of international relations and the international system.

70年来，我们的世界总体保持了和平稳定，人类的发展事业更是取得了前所未有的进步。但与此同时，随着全球化时代的来临，随着国际力量对比的演变，现有国际秩序和体系也日益面临新的挑战。比如联合国宪章的宗旨和原则往往得不到真正遵守，国际关系中各种不公正的现象依然时有发生。特别是近年来，经济低迷、地缘动荡、恐怖危机、文明摩擦，各种乱象此起彼伏，有西方学者甚至惊呼，我们正在走进一个“失序的世界”。

The past seven decades has witnessed overall peace and stability of the world and unprecedented progress in mankind’s development. At the same time, globalization and the shift of international forces have posed new challenges to the existing international order and system. We have seen, more often than not, the purposes and principles of the UN Charter not being observed to the letter, and equity and justice in international relations not honored as people would have hoped. In recent years, in particular, countries in the world have had to cope with a sluggish global economy, geopolitical turbulence, the threat of terrorism and friction among civilizations, to name just a few. No wonder some western scholars have cried out that we are about to enter a world of disorder.
