Abstract: The article examines the relationship between economic diplomacy and economic security of states in the current conditions of global instability. It is determined that effective economic diplomacy is becoming a key tool for protecting national economic interests at the foreign policy level. The emphasis is on the role of diplomatic mechanisms in preventing economic threats, diversifying foreign economic relations and forming strategic alliances. In the context of the war in Ukraine, sanctions conflicts, energy challenges and trade restrictions, the need to strengthen integrated interaction between the diplomatic apparatus and economic security structures is substantiated.

Geopolitical instability, accompanied by military conflicts, economic sanctions, transformation of world markets and disruption of global supply chains, significantly changes the conditions for the functioning of national economies. In such conditions, traditional instruments of public administration lose their effectiveness, which requires the use of new approaches to ensuring economic security, in particular through the intensification of economic diplomacy.

At the same time, there is a certain fragmentation in the scientific literature in covering the relationship between economic diplomacy and economic security. The vast majority of studies focus either on the foreign economic aspects of diplomatic activity or on issues of internal economic stability, leaving out of consideration the systemic interaction between these two areas. The lack of a comprehensive approach complicates the formation of an effective state policy strategy in conditions of constant influence of external threats. This problem is especially acute for states that are in a state of armed conflict or have significant economic and political dependence on external partners. Ukraine is a vivid example of a country for which an effective combination of economic diplomacy tools and measures to ensure economic security is not just desirable, but necessary for survival, recovery and development. Thus, there is a need for a deeper analysis of the mechanisms of systemic interaction of economic diplomacy and economic security, their mutual influence in conditions of external challenges and the definition of practical recommendations for strengthening this interaction in the Ukrainian context.
