Abstract: This article is devoted to the research on interaction of state and financial-industrial groups (FIG) in implementation of foreign policy. Analysis is conducted on the theoretical grounds for interaction between business and state from the position of advancement of national interests. In the recent decades, the influence of private capital upon foreign policy and economy has grown significantly. States use the transnational corporations as an instrument for influence on the international arena, while FIG carry substantial political and economic weight, able to influence domestic and foreign policy of specific states. Based on the conducted research, the author concludes that the mechanism of interaction between business and state is complex and multifaceted. The goals and interests of the state and private capital on the international arena do not always coincide, forcing the parties to constantly search for optimal balance of interests and forms of interaction. The forms and methods of interaction in turn define the character and efficiency of political and economic actions of the state on the international arena.
