Will the Three Seas Initiative Have New European Members?



The Three Seas Initiative members are EU countries; however, some non-EU ones also express their willingness to join.

On 12 January 2021 Moldova’s newly elected President Maia Sandu went on her first official foreign tour. She visited Kyiv, where she met with the Ukrainian President Volodymyr Zelenski. The joint declaration issued by both Presidents contains the following statement: ‘We note the willingness to strengthen co-operation with partner countries in Southeast Europe and the Black Sea region. In this context, we confirm out interest in joining the Three Seas Initiative.’

Participation in the realization of key infrastructural projects should effectively boost co-operation between the Three Seas Initiative member states and neighbouring countries. Poland is the largest among the 3S countries and therefore it could play a key role in initiating such co-operation, especially that several projects planned by those neighbouring countries tally with Polish initiatives. Ukraine and Moldova are now planning to proceed with the construction of a new motorway linking their capital cities, Kyiv and Chișinău. Part of that concept is also a border bridge on the Dniester. Once the motorway is completed, driving between the two cities will take about 5 hours. In 2016, the Polish Ministry of Infrastructure postulated three branches of the Via Carpatia into Ukraine. One of them, the Lublin – Chełm – Lutsk – Ternopil – Vinnytsja – Odessa crosses the planned Kyiv-Chișinău motorway. Two other branches, passing through Lviv to Chernivtsi and farther on to Romania, are situated very close to Moldova, which opens up new connection possibilities.

Another country that the Three Seas states would welcome as a new member of the Initiative is Greece. As Greece is an EU country, co-operation could prove easier than that with Ukraine and Moldova and could perhaps contribute to transforming the Three Seas into the Four Seas Initiative, as Greece lies, inter alia, on the Aegean Sea.

Some co-operation of the Three Seas Initiative with Greece can already be observed. For instance, the planned course of Via Carpatia, linking the north of the Three Seas region with the south, was made longer that originally planned to reach the Greek city of Thessaloniki situated to the south of Sofia, the capital of Bulgaria. At the same time, Austria is getting involved in Greek railway logistics. Two years ago, a Rail Cargo Group subsidiary started transporting goods to Greece. The company is also actively creating a delivery chain, forwarding goods into and out of Greece. Another country interested in Greece’s accession to the Initiative is Bulgaria; this is due to pipe transport and Greek LNG terminals. Bulgaria’s President Rumen Radev emphasizes his country’s co-operation with Greece in the gas sector. As the Southern Gas Corridor will pass through the Greek territory, Bulgaria is keenly interested in availing itself of these opportunities; it is said that Greece could become its main supplier of natural gas.

The development of the Three Seas Initiative now depends on intensified co-operation between its members and inclusion of new members. The described directions of geographical expansion of the Initiative offer new possibilities of economic growth for all Three Seas member states.

The Three Seas Local Government Congress under the Honorary Patronage of the President of Poland



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.
