Abstract: The object of this research is the activation of the Asia-Pacific political vector of Russia. The East development plan declared by the President in 2013 alongside the foreign policy turn of the Russian Federation towards the East due to the current crises of the system of international relations, created the additional prerequisites for close integration of the Russian Federation and its Far Eastern subjects with the Pacific Rim countries. The authors assume that the activity of the Russian Federation within the framework of the international institution of BRICS, which membership Russia has for over a decade, falls within the concept of modern eastern policy of Russia. For revealing the institutional potential of Russia for realization of its “eastern” political vector through BRICS, the authors analyze the participation of Russia in the integration processes in the East, as well as the interests of the key players of the “five”. The scientific novelty lies in application of the complementarity approach of BRICS mechanism and pursuance of its leading actors, including Russian Federation, towards realization of the “eastern” foreign policy vector. The researchers believe that in the conditions of global tension, the institutional potential of BRICS will encourage Russia’s integration into the Pacific Rim.
