The primary objective of this article is to construct a comprehensive conceptual definition of "post-capitalism." The contemporary global landscape, characterized by post-modernity, is currently undergoing a profound institutional crisis. This crisis impacts both its economic underpinnings, rooted in the dominance of financial capitalism, and its societal foundations, which revolve around a universal model of social development built upon a uni-versalist model of consumption. Discourses surrounding post-capitalism within Russian and Western academic and expert cir-cles exhibit unique characteristics. However, they share common traits. On one hand, these discourses reflect an acknowledgment of the impasses inherent in existing models of glo-balization. On the other hand, they recognize the transformation of capitalism as a universal socio-economic system that forms the bedrock of international relations. This article under-scores the inescapable rise of non-economic factors influencing socio-economic systems' development, including their role in shaping international relations. Post-capitalism is best understood as a collection of principles guiding spatial organization and the establishment of economic and political relationships within these spaces, rather than a specific developmental model. Positioned as an element within the broader return to a spatiality, post-capitalism is predominantly discussed within the context of international processes, serving as a transitional phase in international political and economic relations. © 2024, MGIMO Universty Press.
