3SI Summit and Business Forum in Vilnius

15 March 2024

Lithuania has taken over the presidency of the Three Seas Initiative (3SI) from Romania and will be the next Baltic state to host the 3SI Summit being an integral component of the 3SI – International Business Forum on 11 April 2024 in Vilnius.

On 11 April this year, Lithuania will host the 9th summit of the 3SI Initiative, bringing together the 13 member states, associated members of the initiative as well as businesses and investors. Representatives from the government administration will be hosted at the Business Forum. During the one-day event for business, topics relevant to the entire region will be discussed, including security, energy security and transport connectivity. The most significant projects transforming the region will be presented, which are open to entrepreneurs, as well as B2B/B2G meetings will take place.

Participants at the annual Business Forum will discuss the long-term objectives of the 3SI, with particular emphasis on energy security and climate change, the advancement of a neutral economy, the improvement of transport, the consolidation of transatlantic cooperation and support for the integration of associated EU member states, notably Ukraine and Moldova.

The 3SI Business Forum will include a more extensive discussion of projects reshaping the region, such as the Rail Baltica project, directly involving five EU member states: Poland, Lithuania, Latvia, Estonia and Finland, as well as multilateral road infrastructure projects such as Via Baltica and Via Carpatia. The Business Forum will also address the integration and synchronisation of the Baltic electricity system with European grids, and other important strategic projects for renewable energy and interconnection in which business can participate.

The 3SI Business Forum represents a unique format where decision-makers and the business community can come together to address discussions on energy, transport infrastructure, digital interconnectivity and other issues relevant to the region. It is an excellent arena for establishing new business contacts between the business communities and 3SI partners in Europe, the US and other states in the joint pursuit of innovative solutions. The vision of Lithuania, as the 3SI presiding state, is a strong Europe and strong transatlantic ties, said the President of the Republic of Lithuania, Gitanas Nausėda, referring to the business forum to be held in their capital.

To date, there have been a total of eight summits in seven countries: Croatia, Poland, Romania (twice), Slovenia, Estonia, Bulgaria and Latvia. Lithuania (2024), Hungary (2025), the Czech Republic, Slovakia, Austria and Greece are still to come.

The 3SI brings together 13 European Union Member States: Austria, Bulgaria, Croatia, the Czech Republic, Estonia, Hungary, Latvia, Lithuania, Poland, Romania, Slovakia, Slovenia and Greece, and 2 associated countries – Ukraine and Moldova. The strategic partners of 3SI include the USA, Germany and the European Commission.

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.
