Abstract: Cooperation between the Republic of Korea and the Russian Federation traces back to the early 1990s when the countries went into the diplomatic relationship. The countries continue to interact in various spheres: trade and economic, political and cultural. One of the promising areas of their cooperation is the conjunctive use of the Northern Sea Route. The object of this research is the relations between the Republic of Korea and the Russian Federation. The subject of the research is the cooperation between the two countries in terms of the use of the Northern Sea Route. In his research Kim used the main methods and principles of history as a science, in particular, historicism, consistency and accuracy. These methods allow to analyze historical processes from the point of view of their development and interrelation as well as to carry out multi-aspect analysis of facts and events. Based on the research results, the author makes a conclusion that the countries became interested in cooperation at the end of the last century already when they discussed the project of gas line construction, and up to now the Republic of Korea and the Russian Federation have been actively interacting regarding the conjunctive use of the Northern Sea Route. Both sides are interested in developing their cooperation further. The novelty of the research is caused by the fact that for the first time in the academic literature the author carries out a complex analysis of the interaction between the Republic of Korea and the Russian Federation regarding the development of the Northern Sea Route.
