The year 2025 was marked by deepening contradictions between the leading world powers in world politics and economics. The dominant paradigm is the transition of the world's leading players, primarily the United States, to fierce competition in order to promote and realize national interests. In this context, political polarization has increased in many countries of the world and the internal political struggle has intensified. The book contains materials on the most pressing issues of the modern international agenda, security issues and trends in the development of the global economy. Considerable attention is paid to the political and economic processes in the USA, China, India, Japan, Germany, Britain, France, Iran, Turkey and other leading countries of the world.
