International and National in Contemporary Private Law

Private international law as a branch of law still causes discussions regarding its subject, nature and sources. Therefore, all these as yet unresolved problems, having practical importance and theoretical interest, still require attention. The study is carried out using such methods as synchronous and diachronic comparative legal, historical, legal-linguistic, dialectical-materialistic, descriptive, analysis and synthesis. The present article is devoted to the main trends in the development of private international law in modern conditions from the point of view of the ratio of domestic (national) and inter-state (international and supranational) regulation. A brief historical overview provides the key to a better understanding of the current state of affairs. The competition of several factors contributing to the internationalization and nationalization of private law is one of the objects of exploration in the article. The development of private law is characterized by mutually contradictory trends, which, on the one hand, show the strengthening of the internationalization of legal regulation, and on the other hand, reflect the consolidation of the nationalization of legal means of streamlining the interaction of individuals and legal entities.
