Warsaw. 10th Three Seas Summit

03 June 2025

The 10th jubilee Three Seas Summit took place at the Royal Castle on April 29, 2025 in Warsaw. President of the Republic of Poland, Andrzej Duda hosted a Summit.

We are meeting today to celebrate the tenth anniversary of the Three Seas Initiative, an initiative that arose from the need for deeper integration, primarily economic and infrastructural, in our part of Europe—Central Europe, said the Polish president during the opening session of the Summit.

The format is now a decade old and the Three Seas Initiative has strengthened its function as one of the important tools for strengthening transatlantic relations in both the political and economic dimensions.

At the same time – as Andrzej Duda emphasised – as a project of the countries belonging to the European community, the Three Seas Initiative – also through actions aimed at deepening Euro-Atlantic relations – enriches and strengthens the European Union.

At present, the Three Seas Initiative comprises 140 priority projects, two investment funds and another in the design phase, as well as an extensive network of partnerships and many bottom-up initiatives covering regional, scientific and economic cooperation. Among the most important from the perspective of the strategic interests of the Republic of Poland are: gas interconnectors with Lithuania and Slovakia, the Via Carpatia expressway, the rail corridor of the TEN-T Baltic-Adriatic core network, Rail-2-Sea – rail connection between the ports of Gdansk and Constanta.

In the afternoon, President Andrzej Duda, at a joint press conference with Lithuanian President Gitanas Nausėda and Croatian Prime Minister Andrej Plenković, summed up the meeting of heads of state and government at the 10th Summit of the Three Seas Initiative.

The 6 th edition of the Three Seas Local Government Congress will be held May 27-28, 2026, under the Honorary Patronage of the President of the Republic of Poland, Karol Nawrocki. This distinction recognises the growing importance of the event, which has become a key platform for cooperation among the countries of Central and Eastern Europe, both in the economic and infrastructural dimensions.

Over five editions of the Congress (2020–2025), more than 5,000 participants from 24 countries have taken part, 104 discussion panels have been held, and 64 foreign delegations have visited Lublin. The scale and international character of the event confirm its increasing role in shaping dialogue across the Three Seas region.

We, the countries representing Central and Eastern Europe (…) through the Three Seas Initiative, Via Baltica, and Via Carpatia, share not only our voice and vision of building a civic community, but also tangible results showing that the Baltic States and the countries of Central and Eastern Europe are capable of implementing major infrastructure projects, emphasised President Karol Nawrocki during his visit to Vilnius last month.

These words perfectly capture the spirit of the Three Seas Congress, which brings together political, academic, and business communities around a shared goal, building a strong, integrated, and cooperative Central and Eastern Europe.

It is also worth noting that in April 2025, Poland hosted the 10th Three Seas Initiative Summit. During the event, participants emphasised the importance of infrastructure and economic cooperation in the region and the need to strengthen cohesion across Central and Eastern Europe. This year, the cooperation format has been expanded to include new members – Albania and Montenegro joined the Three Seas Initiative in the capacity of associated participating states, while Spain and Turkey became new strategic partners. It has already been announced that the 11th Summit will take place in Croatia in 2026.

We cordially invite you to take part in the Three Seas Local Government Congress! Registration will open in the end of January. More details will soon be available at www.congress.lubelskie.pl and on our social media channels.
