As the geopolitical competition between great powers intensifies significantly and the global economic situation becomes grim，the global South’s economic rise，political consciousness and diplomatic independence continue to improve，and it is becoming a key player affecting the trend of the world structure. China，India and other emerging powers have actively promoted practical cooperation in various fields among countries of the global South and increased the representation and voice of developing countries in the global governance system. The developed countries have also recognized the importance of the global south and strengthened their partnerships with some countries of the global south at various levels，including economy，politics and security. Countries in the global South still face many challenges，such as rising economic inequality，group heterogeneity，western fragmentation and co-opting，and the dilemma of collective action. Looking ahead，the global south can make further use of existing platforms such as the BRICS countries and the New Development Bank to build deeper and operational partnerships and meet the common aspirations of countries in the global south for development and revitalization.
