In September 2017, China hosted the Xiamen summit of BRICS. This is the second time China has been leading and shaping the cooperation of developing countries and the direction of global governance. At this summit, China successfully introduced the concept of “BRICS +” cooperation as the president of BRICS summit. This is not only conducive to the realization of the integration of the Chinese concept and the connotation of BRICS, but also to alleviate the differences as of the “expansion”. In the future, China will take the “BRICS +” platform as the main line to promote the construction of global partnership. Through promoting dialogue and liaison with regional organizations and international mechanisms, we will explore feasible ways to enhance coordination and cooperation with middle powers. China should maintain the development of global governance and strengthen the carrier of cooperation with the G20 mechanism, and then achieve the ability to enhance the decisionmaking power and execution of the BRICS mechanism. At the same time, China can also achieve the goal of releasing the vitality of the BRICS cooperation and expanding the cooperative influence of the BRICS.
