At the turn of the 20th and 21st centuries the Arctic region has become one of themost important centers of concentration of various international interests: economic,geopolitical, academic research, environmental and many others. But at the same time,the corresponding problems coincide with the interests of different states: the disputesthat arise between states about the legal status of certain maritime areas in the Arcticentail legal uncertainty as to the legitimacy of the extraction by representatives of a givenstate of marine living or mineral resources, the jurisdiction of the state in certain maritimeareas, as well as bringing to responsibility for damage to the natural environment and manyother issues arising in connection with human activities in the Arctic region. Moreover,at the beginning of the 21st century, such a problem arose as a disagreement betweenthe Arctic and non-Arctic states regarding the extraction of marine living resources in theArctic Ocean and the development of hydrocarbon deposits on its continental shelf andin the International Seabed Area of this ocean. To resolve and further prevent disputesarising between states in connection with their activities in the Arctic, it is necessaryto analyze the mechanism of cooperation between them in the region at all levels ofinternational legal regulation: universal, regional and subregional. Having explored themechanism of international cooperation, it is possible to designate the following: at eachlevel of international legal regulation, there are international treaties and internationalorganizations that are called upon to implement them, in the Arctic region. But at the sametime, the levels of legal regulation of the Arctic regime are not linked, because there is nodirect relationship either between treaties adopted at various levels, or between bodiesor organizations functioning in accordance with such treaties. It is also important to notethat many sectoral cooperation in the Arctic region have not yet been resolved at all oronly partially resolved. In this connection, it seems appropriate to conclude internationaltreaties aimed at regulating cooperation on specific (sectoral) issues: the legal status ofthe peoples of the Arctic, the development of mineral resources, the extraction of marineliving resources and the protection of the environment.
