The modern world economy is characterized by such factors as capital mobility, intensification of production processes and cash flows. In such circumstances, it is particularly important for economic entities to understand all possible legal consequences of their operations. Financial policy should be formed by public legal entities, taking into account the guarantees of avoiding unjustified financial, economic and other barriers to the development of the world economy and international trade. The BRICS countries, which have a huge potential for building and developing close economic ties, have different and sometimes contradictory law enforcement and legislative approaches. Such contradictions are most acute in the tax sphere, currency, administrative and customs relations. The current international legal framework seeks to bring legal regulation closer to comparable or uniform rules.
