ABSTRACT
Western scholars studying international relations systematically included the practice issue into an international relations study in 2000 and put forward the practice theory of the international relations study. Practice theory is also meaningful to perfect and promote the major-power diplomacy with Chinese characteristics. The development roadmap mainly strived to complete a series of key steps concerning the success of the Brazil, Russia, India, China and South Africa (BRICS) mechanism cooperation through the summits. The concept of the BRICS mechanism was put into practice with the joint effort of China and the other BRICS countries. China's collective identity as a founding member of the BRICS mechanism with equal rights and reciprocal obligations was firmly established. According to the analysis, clear logic of practice has been shown in China's participation in the establishment and development of the BRICS mechanism.
