The Three Seas Initiative as a Political Challenge for the Countries of Central and Eastern Europe

The Three Seas Initiative (TSI) is an informal association that focuses mainly on the economic integration of EU member states through the cooperation of specific sectors. It is meant to strengthen the single market and bonds among countries in Central and Eastern Europe. It also seeks to reduce developmental differences between these countries and the older EU member states. This study explores the background of the TSI, which was jointly conceived by the presidents of Poland and Croatia with the goal of strengthening ties among countries in the area between the Black, Baltic and Adriatic seas. The association brings together 12 states across Central and Eastern Europe and the Balkans: Poland, the Czech Republic, Slovakia, Hungary, Lithuania, Latvia, Estonia, Croatia, Slovenia, Bulgaria, Romania and Austria. As well as enhancing their political ties, it aims to develop cross-border cooperation and implement macro-regional projects. The analysis highlights both the diverging interests of the TSI countries and their common predicament. These states are connected by the fact that they stand to lose the most from the two-speed Europe idea that some Western politicians have imposed. They are also at a clear disadvantage when it comes to infrastructure investments. In the past, the European Union has emphasized East–West cooperation and overlooked the North–South communication and energy corridors. The Three Seas Initiative founders are trying to determine the best form of cooperation for the Central and Eastern Europe region.
