In recent years the relationship within Russia-China-Japan triangle has become an increasingly important factor of the political situation at the Asia-Pacific region. Being important parts of the regional subsystem, Japan and China largely determine the balance of power in East Asia. Taking into account the specifics of these countries relations, the existence of unresolved conflicts between them, Russia seeks to maintain stability in the region, including participation in joint projects - economic, military, scientific, etc. Constructive dialogue in the triangle of Russia-China-Japan meets the geopolitical goals of our country. In the context of comparative politics, the article examines the trends of the Russian-Chinese and Russian-Japanese interrelations, as well as their hierarchy in Russia's strategic interests. The authors come to the conclusion that a "post-West" model of intercountry relations is gradually being formed in the region. This model takes into account the interests, features of the socio-political and economic system of its member states, and also helps to smooth out conflicts between the parties, and contributes to world development as a whole.
