This year marks the 55th anniversary of the United Nations General Assembly Resolution 2758, a pivotal milestone that made the one-China principle a fundamental norm governing international relations and a broad consensus of the international community. This landmark achievement has significantly enhanced China's engagement in UN affairs, thereby amplifying the voice and influence of developing nations.

　　The adoption of the resolution highlights the interplay of shifting global power dynamics, coordination among UN members, and multilateral institutional processes, and is a historical reference for collective action by the Global South today.

　　The current cooperation among Global South countries on development reflects their growing ability to engage in international affairs. This progress is supported by the representation and consultation channels provided by international institutions, and by sustained economic and social development and collective action.

　　Despite differences, these countries share common concerns in development financing, trade opportunities, technology access, and representation in international bodies. Collaboration with China enhances local development and global governance, strengthening their influence through institution building and international discourse.

　　Trade cooperation underscores deep economic ties, with South-South trade reaching $7.2 trillion in 2025, accounting for 28 percent of total global goods trade. China's vast market, comprehensive manufacturing system, and supply chain linkages offer developing countries access to industrial goods, production means and market opportunities. As cooperation deepens, these trade relationships are poised to enhance export diversification, industrial upgrading, and value-added growth.
