Abstract: Over the past few decades, the global economy has undergone profound transformational changes that have impacted all structural subsystems. These changes have increasingly encompassed the fundamental processes of capital and production monopolization. In the first quarter of the 21st century, these processes have assumed a distinctly global dimension, extending across national economies, stages of social reproduction, and all sectors of the world economic system. Under conditions of mounting geo-economic uncertainty, heightened volatility in the global economic environment, and intensified international competition for access to raw materials and consumer markets, multinational corporations are progressively reliant on institutional mechanisms that support their economic interests in international commodity and investment markets – most notably, through the practice of corporate diplomacy. This article conceptualizes the essence of corporate diplomacy and delineates its institutional architecture. Particular emphasis is placed on its role and significance within the broader framework of strategic dialogue between nationstates and global corporations. It is argued that contemporary corporate diplomacy functions at both national and regional levels, encompassing flexible formats of public-private partnership that aim to facilitate the internationalization of national producers. The coordinating role of the state is underscored as central to this process, alongside the pivotal contribution of various representative, advisory, consultative, and dialogical platforms that foster inclusive engagement between governmental and business actors. The article offers a comprehensive assessment of the roles played by chambers of commerce, business associations, independent consortia, and non-governmental, non-profit organizations in facilitating cooperation between executive state agencies and business entities in the formulation and implementation of foreign economic policy at both national and regional levels.
