Building a community of shared future for mankind is a Chinese solution for global governance. The global governance system consists of three levels: normative principles across issues, international institutions in various issue areas, and informal dialogue mechanisms. The community of shared future for mankind is institutionally supported by a new global governance system, which consists of three levels: the common values of all humankind as normative principles, international institutions that integrate commonalities, and an informal dialogue mechanism based on multilateralism. China has actively advocated the concept of a community of shared future for mankind, and has comprehensively utilized various pathways to participate in the reform of the international system, with the Belt and Road Initiative (BRI) as a practical platform to create a leading effect. Promoting the building of a community of shared future for mankind is a long-term project, and China will continue to promote reform of the global governance system under the guidance of the concept of a community of shared future for mankind.
