Abstract
The article deals with the understudied issue of the formation and development of the Kazakhstan-Russia relations, which began to be established just after the collapse of the Soviet Union and the formation of the Commonwealth of Independent States, where the Russian Federation and the Republic of Kazakhstan held a special place. The analysis reveals that in their mutual relations both states gave priority to the development of cooperation in the field of economy as the most pressing issue after the collapse of the Soviet national economy. At the same time, as it is shown in the article, special attention was paid to the development of the two countries' political, defense, and other relations, which currently have crucial significance.
