The article presents aspects of the legal characterization and regulation of the natural resource’s treatment that are under the joint tenancy of two or more states. The scientific novelty of the study is determined by that fact that shows the aspects of international interaction and the formation of the practice of legislative regulation of the use of natural resources, not only in the field of state and legal regulation but also within the context of private-public partnership. The relevance is determined by the fact that the main problem of the development of energy resources is an opportunity to determine and accordingly implement certain provisions for international business enterprises. The purpose of this article is to study the question of how representatives of international business can implement projects for the extraction of natural resources across boundary areas and under various conditions within the framework of cross-border cooperation. In the work, the methods of mathematical statistics, historical and legal methods were used. A three-level model was presented. This model determines the possibility of ensuring cooperation, then it forms its legal and regulatory framework and then determines instruments of an economic and legal nature that can be implemented in this field. The final point of the model is the finding of opportunities for investing in the development of natural energy resources on a parity basis, as well as the formation of an integrated environment that determines the possibility of integrating the subjects of international business into the economic environment of the state.
