Promoting the building of a community with a shared future for mankind is Chinas plan to improve the global governance system. It is also a blueprint for the world based on human history, reality, and development trends. It is the only choice for planning the destiny of mankind in the 21st century. The reason why the community with a shared future for mankind is the right way in the world is that this plan is not for the benefit of a country, but for the sake of mankind; it is not for the benefit of the moment, but for the sake of future generations. Building a community with a shared future for mankind has innovated the way of thinking of global governance, opened up a grand vision of world order, marked the future direction of Chinas diplomacy, and opened up a new form of human civilization.
