The article covers the combination of two large-scale integration projects, the Great Eurasian Partnership (Russian Federation) and the initiative called One Belt, One Path (People’s Republic of China). Following the joint statement of the People’s Republic of China and the Russian Federation dated 5 June 2019, which sets out the fundamental provisions of a comprehensive partnership and strategic interaction between the two countries, the author states that the cooperation between Russia and China is conditioned by a number of the political, economic, cultural, and geographical factors; that it can bring tangible benefits not only to Moscow and Beijing, but to almost the entire Eurasian continent, as well as stabilise the global situation. However, in the process of their interaction Russia and China constantly encounter various obstacles, which manifest themselves at the bilateral, regional, and global levels and significantly slow down the implementation of joint projects, which are mutually beneficial. In this work, the author proves that the cumulative intensifying effect on the cooperation between Russia and China can be provided by the strategy of “pairing” integration projects of Russia and China, which the parties have been implementing quite consistently and steadily since 2014.
