Abstract: The border between the Republic of Kazakhstan and the Russian Federation is the longest land border in the world and is 7,400 kilometers long. When establishing diplomatic relations, Kazakhstan and Russia left the borders inherited from the USSR unchanged. They declared the absence of territorial disputes, the inviolability of territorial integrity and the recognition of each other's sovereignty. Negotiations on the delimitation of the border began at the end of 1999 and lasted five and a half years. The rich natural resources of the border area, as well as the construction of railways, roads, settlements and industrial centers in the border areas without taking into account the administrative border in Soviet times, the display of the border between the Kazakh SSR and the RSFSR only on duty maps of adjacent regions without approval by the supreme authorities of the Soviet Union complicated the processes distinctions and required painstaking work. To resolve these issues without infringing on the territorial integrity of states, government delegations and working groups of the sides held a total of 50 negotiations. In January 2005, they signed an agreement on the state border of Kazakhstan and Russia. The article deals with the international legal formalization processes of the Kazakh-Russian state border. The authors extensively analyzed the problems that arose during the delimitation process and their solutions, as well as considered the impact of the geopolitical situation on the border demarcation at that time and the territorial integrity policy of the states.
