Abstract: Diplomatics has always been interconnected with economy particularly the development of international trade. However, unlike the previous historical periods, the era of global interaction, developing an intense economic competition, simultaneously contributes to growth of interdependence between economic systems of various countries. Thus, there arises a legitimate question: whether or not the professional diplomats and experts in international relations should be concerned with the state economic administration. What are the practical and theoretical grounds for studying economic coercion from the position of world politics and science on international relations? It is suggested that such articulation of the problem initially implies presence of an objective need for detailed analysis by the expert-analytical community of economic sanctions (same as other instruments of economic coercion) in the context of global and regional international politics. The goal of this research consists in conceptualization of the term “economic sanctions” as a category of international-political science in light of its more relevant analytical angles and theoretical-methodological approaches. A conclusion is made that the effective application of economic sanctions as a regulatory instrument for international politics is often overestimated. The states that initiated sanctions launch a sanction mechanism in such instances, when they do not see other alternatives for various reasons. Sanctions become successful when imposed by an entire coalition, rather than a separate country; then in can affect the political elites and not only the regular citizens. The scientific novelty and practical importance is defined by the fact that the acquired results can be used in scientific and pedagogical activity in studying specific forms and methods of realization of economic diplomacy in Russia and foreign countries, as well as can be of interests for the experts in international political and economic cooperation.
