The concept of a “community with Shared Future for Mankind” was first proposed in China and has quickly become an integral part of discussions on international relations and global governance. This concept originates from China’s profound insights into the interdependence of nations in the context of globalization, recognizing that the fates of countries are closely interconnected when facing global challenges. With the shifting balance of international forces and the increasing severity of global issues, traditional mechanisms of global governance have shown certain delays and inadequacies. From the difficult birth of climate change agreements to frequent conflicts in international security, from the uneven development brought by economic globalization to the ethical and management issues of emerging technologies, the structure of global governance faces unprecedented challenges. This paper focuses on the research question of how the concept of a “community with Shared Future for Mankind” aligns with and transcends the existing global governance system, using theoretical analysis and practical references for discussion. The findings suggest that the concept provides new ideas and frameworks for addressing global challenges such as climate change and international security, promoting the democratization and efficiency of global governance, especially in enhancing the representativeness and discourse power of developing countries in global decision-making. Additionally, the research identifies the transcendent nature of the concept in global governance, aiming to offer possible directions and strategies for the future development of global governance.

The continuous development of emerging economies represented by China and Russia has exacerbated the changes in the world political and economic landscape, and international organizations represented by the United Nations have led to inefficient dispute resolution mechanisms in international affairs due to their formalism and pluralism. On the contrary, G-groups has shown its flexibility and efficiency in global governance. However, the international community has been questioned G-group’s legitimacy for many years. This paper will take the G7 and G20 as examples, analyze the legitimacy problems in G-groups, explain their reform measures, and propose future reform directions to promote the development of G-groups, so as to help the international community to conduct global governance more effectively.
