The expansion of BRICS is the result of the connection between the supply side and the demand side of the BRICS cooperation mechanism under the changes in the international en-vironment.On the demand side,the BRICS cooperation mechanism can provide new interna-tional legitimacy for the countries of the"Global South"to pursue a path of modernization that suits their own realities,and provide a new international institutional platform and ca-pacity path for shaping a new international order and accelerating the reform of the global governance system.On the supply side,the expansion of the BRICS cooperation mechanism has benefited from appropriate institutional design and the construction of norms with high in-ternational recognition.The expansion of BRICS will open up more space for the"Global South"to jointly move towards modernization through exchanges and mutual learning among civilizations,provide stronger impetus for promoting a universally beneficial and inclusive economic globalization,lay a more solid foundation for promoting the equal and orderly multi-polar world,and enhance the collective action power of the"Global South"in promoting the reform of global governance.In the long run,the BRICS cooperation mechanism needs to over-come a series of internal and external challenges,achieve a balance between"widening and deepening",and enhance the institutional potential of the BRICS cooperation mechanism.
