The article considers the importance of international negotiations in the context of changes that have been occurring in international relations, especially after the First World War. The article is divided into four sections that show qualitative changes in the international negotiations in the context of changes which indicate progress in the development and deepening of international relations. In the first chapter, I discuss international opportunities that favor the intensification of international negotiations. The second chapter discusses the actors of international negotiations, indicating that with the evolution of international relations, there expanded the circle of influential participants in negotiations. The fundamental assumption of the third chapter is that with the evolution of international relations, international negotiations have begun to provide a process consisting of several stages with different dynamics rather than limit themselves to a traditional single meeting at the negotiating table. The fourth chapter refers to the determinants of negotiating process, which are diagnosed in different dimensions: structural, institutional, strategic, cultural and psychological.
