"In the world, there is only one international system, i.e. the international system with the United Nations at its core. There is only one international order, i.e. the international order underpinned by international law. And there is only one set of rules, i.e. the basic norms governing international relations underpinned by the purposes and principles of the UN Charter," Xi stressed.

All countries should act in accordance with the purposes and principles of the UN Charter, and refrain from pursuing unilateralism and hegemony, and should not use multilateralism as a pretext to form small circles or stir up ideological confrontation, he has said.

The United Nations, he has suggested, "should hold high the banner of true multilateralism and serve as the central platform for countries to jointly safeguard universal security, share development achievements and chart the course for the future of the world."

Citing the 50th anniversary of the restoration of China's lawful seat in the United Nations, Xi told the UN General Assembly in September that China will "continue our active efforts to take China's cooperation with the United Nations to a new level."

"China is always a builder of world peace, contributor to global development, defender of the international order and provider of public goods," he said. "China will continue to bring the world new opportunities through its new development."
