受不合理国际政治经济制度的制约，20世纪后半叶兴起的南南合作并未给南方国家带来预期的发展。自新千年以来，以金砖五国为代表的新兴经济体的迅速发展冲击了既有的国际政治经济格局。作为新时期南南合作的典范，金砖合作机制的成果与影响力在近十年不断发展。而“金砖+”机制的创立进一步提升了金砖合作向南方国家的开放性，为将金砖合作打造成新时期最具代表性的南南合作平台提供了理念和制度的支持。
Bound by unreasonable international political and economic institutions，the South-South Cooperation （SSC） that emerged in the second half of the twentieth century did not bring the expected development to the global South. Since the new millennium，the rapid development of emerging economies，especially the BRICS countries，has impacted the existing international political and economic structure. As a leading model of SSC，the achievements and influence of the BRICS cooperation have continued to develop. The establishment of the ‘BRIC Plus’ mechanism has further enhanced the openness of BRICS cooperation to other Southern countries and has provided ideational and institutional support for making the BRICS cooperation the most representative platform for SSC in the coming period.
