Lublin Triangle – a new coalition for Europe

10 December 2021

A two-day 11th session of the Parliamentary Assembly of Sejm and Senat of the Republic of Poland, Seimas of the Republic of Lithuania and Verkhovna Rada of Ukraine (Supreme Council of Ukraine) is being held. The Chairman of the Lithuanian and Ukrainian parliament Viktorija Čmilytė-Nielsen and Rusłan Stefanczuk have harmoniously stated that cooperation within the Lublin Triangle is essential for joint security.

On Monday, there will also be a meeting of the commission for European and Euro-Atlantic integration of Ukraine, the commission for development of trade and economic, regional, local and transborder cooperation, commission for security cooperation, as well as the commission for social and cultural cooperation.

Works within particular commissions will lead to elaborating a joint stance on the most important issues for the Lublin Triangle states. As part of works of the commission for European and Euro-Atlantic integration of Ukraine it will also be possible to work out a joint strategy for integration of Kiev with Western structures. Poland and Lithuania, as members of the UE and NATO, are lobbying for euroatlantic integration of Kiev.

Another issue developed within the commission for trade, economic, regional, local and transborder cooperation is energy security of the Lublin Triangle states, who are constantly experiencing a permanent pression from Russia with this regard.

The commission for social and cultural cooperation aims to work out proper mechanisms, which will let counteract Russian and Belarussian fakes news aimed at the UE and NATO states.

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.
