The article is devoted to the political and economic analysis of the interconnectedness of the main international entities formed with the participation of the Russian Federation in the Eurasian space. The authors substantiate the specific features of the development of the most important entities - the Shanghai Cooperation Organization (SCO), the Eurasian Economic Union (EAEU) and the informal association of the countries of the Caspian region. At the center of the study is the Eurasian Economic Union, which is represented by the post-Soviet and, in essence, is the middle Eurasian space, within which the Great Eurasian Partnership and its megaprojects of development are being formed. The place and role of each association in transformational transformations in the space of Greater Eurasia is substantiated. Within the framework of the indicated configuration of international entities, approaches to pairing their geopolitical and economic areas, as well as the most important development segments, are considered. It is proposed to use the formula of parity, complementary partnerships represented by the proportionality of Chinese financial, economic and technological support in combination with Russian military - strategic (nuclear and non - nuclear) parity, as well as maintaining global and regional stability and security.
