Abstract
This article analyzes the problems of world security in the context of the formation of a multipolar system of international relations taking place on the basis of changes in geopolitical conditions in the modern world. The Covid-19 pandemic has led to some global changes. One of them is the tendency of the multipolar system in international relations. In accordance with the changes taking place, political reality takes on a different look, faces new threats and leads to systemic instability. One of them is the issue of international security. One of the most important features of the multipolar system is its unpredictability, which is due to the fact that it takes place not only in world, but also in regional competition. The article shows that ensuring international security in a multipolar world is a long and complex process, where, in addition to measures to establish mutual understanding and cooperation between the main actors, it is also necessary to improve international institutions and mechanisms for resolving international conflicts. This article is based on the emergence and direction of the multipolar system, its close connection with the issue of security in international conflicts.
