The relevance of this article is the further expansion for studying the role of the Kalmyk Khanate in Russia's eastern policy, especially in the eighteenth century, when the khanate was at the top of its development. This is important not only for the history of the Kalmyk people proper, but also for highlighting the participation of the peoples that were part of Russia, in its foreign policy activities in this or that period. The purpose of the article is to prove the contradictory nature of relations between Kazakhs and Kalmyks in the second quarter of the 18th century on the basis of the new materials of the Archive of the Foreign Policy of the Russian Empire and the National Archives of the Republic of Kalmykia. Tracing the ties of the Kalmyk khanate with the neighboring nations and states in the east, mainly with Kazakh zhuzes, the author proves that under the control of the Russian state the role of the Kalmyk khanate in the eastern policy of Russia has gradually increased. This is the scientific novelty of the work.
