3SI Summit and Business Forum in Vilnius



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.
