Bucharest, ROMANIA

6-7 SEPTEMBER 2023


Welcome to the Three Seas Initiative (3SI) – a politically inspired, commercially driven platform for improving connectivity between twelve EU Member States allocated between Baltic, Adriatic and Black seas.

The Three Seas Initiative was born out of a shared interest in developing transport, energy and digital infrastructure connections on the EU’s north-south axis. Connections that must be trusted, sustainable and inclusive thus strengthening EU cohesion and enrich transatlantic links. 3SI aims to scale up region’s excellence EU-wide and globally. 3SI partners – the United States, Germany, and the European Commission – are closely involved in this process.

To improve regions connectivity and accelerate investments in infrastructure projects of the regions 3SI Investment Fund was set up in 2019. To know more about the 3SI projects we invite you to navigate through the list of priority projects.

The Joint Declaration of the Eighth Summit of the Three Seas Initiative (Bucharest, 6-7 September 2023) is available at the following link: https://3seas.eu/media/joint-declaration-of-the-eighth-summit-of-the-three-seas-initiative

Romania took on the role of organizing the 8th edition of the 3SI Summit at a decisive stage for reconfirming the Three Seas Initiative as a political platform for facilitating strategic infrastructure interconnection projects and investments in the region on the North-South axis, thus realizing the 3SI’s goals of developing the economies of participating states, promoting the convergence with the rest of the EU and the transatlantic partnership.  At the same time, the 3SI has to respond to the need of defining the relationship with a geopolitically reconfigured neighbourhood under the impact of the brutal war of Russian Federation against Ukraine. The guiding principles of our agenda stems from the conviction that “together we are stronger”, and this is the spirit of the Bucharest Summit I will host this autumn, on 6-7 September.  Now, more than ever, it is high time to implement the 3SI objectives and deliver concrete results for the benefit of the entire region!
Klaus Werner IOHANNIS President of Romania
