The development of international trade by expanding knowledge, forming an equal legal and technical basis and social and economic conditions, and providing a favorable environment to improve the well-being of society of all participating countries is a priority task of our time. The concept of international trade has been studied for quite a long time. Nevertheless, scientists have not come to an unambiguous result. To develop a fundamental direction for unifying this concept, it is necessary to analyze definitions recommended primarily by international organizations, such as World Trade Organization, Organization for Economic Cooperation and Development. Economists who study international socio-economic relations note that the qualitative content of international trade has changed due to the emergence of alternative new theories of trade, including models of internationalization and globalization. The development and scaling of integration negatively affect the preservation of customs and economic spaces of countries. It is necessary to apply mechanisms of interaction and control of state supervisory bodies and business communities. The basic components of this system are elaborated as a result of the analysis of the conceptual and categorical apparatus in the field of international trade. The authors systematized trends in the development of global economic processes. The authors also formulated approaches to the development of the concept of international trade development, which includes a mechanism for harmonizing the modules of philosophy, digitalization, and policy. In deep contact, these modules involve the reduction of trade restrictions and barriers through legal, organizational, and management measures and the synergy of the three-module relationship. The main aspects of interaction can include the reduction of juvenile barriers, the increase of managerial innovations that bring the parties closer to common goals, the elimination of the effects of subjectivity, and the use of digital and other new technologies in the management of processes. The main provisions of the concept of development of international trade are aimed at deregulating world trade and motivating the development of domestic economies and the competitiveness of subjects of foreign economic activity.
