The study outlines the problematic framework of the emerging field of digital diplomacy in the social, cultural, and economic dimensions through a close reading of Stiegler’s philosophical concept of the techno-culture. The research intends to raise important questions regarding international communications in a new light of phenomenology of collective individuation. Stiegler’s philosophical conception of contemporary politics under the condition of globalized cultural and economic capitalism is one way to explain the dramatic changes in diplomatic relations taking place on the global arena at the beginning of the new century. Stiegler’s techno-cultural project has significant implications for digital diplomacy as a practical discipline and can be successfully utilized to improve its future development based on the more productive engagement with social, economic, and political issues in a theoretical context. The study tries to deepen the understanding of the political and economic mechanisms in the international communication and diplomatic activities complicated and challenged with the advance of digital technologies in the global capitalism system.
