Objectives:
The article focuses on the development of subregional cooperation in Central Europe. The emphasis is on the Visegrad Four format consisting of the Czech Republic, Hungary, Poland and Slovakia. The article tries to answer the question whether it is still beneficial for participating countries to cooperate in the V4 framework. The article also aims to identify both possibilities and constraints that would frame cooperation in the V4 format in the foreseeable future, as well as to suggest some areas of cooperation.

Material and methods:
The approaches of Alexander Wendt's social constructivism are employed. The Visegrad framework of cooperation can be understood as a social structure that changes over time, as its identities and interests gradually change – according to the principle of mutual, constantly ongoing constitution of the structure and actors. The constructivist approach also allows to explain the behavior of individual actors (V4 countries) in different periods of the functioning of the Visegrad Group.

Results:
The willingness of individual countries to cooperate remains to be an essential condition for the functioning of the Visegrad cooperation. The positioning of the V4 countries in the EU and international relations in general, formation of their foreign and security policies, as well as their mutual interaction will play a major role. The impact of external environment and influence of external stakeholders also cannot be neglected.

Conclusions:
The article analysed the Visegrad Group as an interesting example of a subregional cooperation format from the point of view of international relations. The constructivist approach, which was employed, enabled us to identify different phases of evolution of the Visegrad cooperation in the past, as well to suggest possible ways of development in the future.
