One of the relevant aspects of modern international life is combating crime. Among the main threats, corruption plays a key role as a socially negative phenomenon that undermines the economic, social, and political foundations of any given society. Corruption damages national security and at the same time hampers the development of international relations. Corruption undermines states’ credibility as well as destabilizes international economic and political activity. In consideration of this issue, the consolidation of states in the fight against corruption constitutes the priority direction in the development of international relations. The strategic direction of international cooperation in the fight against corruption is the harmonization of criminal legislation. International standards focus on universal principles of combatting corruption. However, international law requires certain conditions for implementation within the framework of national legal systems. The world community is distinguished by a significant difference in the design of criminal law norms. A comparative legal analysis of the criminal legislation of multiple countries indicates a significant divergence in the characteristics of the specific constituent elements of corruption. Consequently, this paper reveals the mechanism of interaction of states in the fight against corruption on the basis of standardization of international legal norms.
