Three Seas Initiative (3SI) — Frequently Asked Questions

What is the Three Seas Initiative (3SI)?

A presidential-level cooperation format of 13 EU member states located between the Baltic, Adriatic and Black Seas, focused on developing infrastructure in three areas: energy, transport, and digital.

Strengthening North–South connectivity, mobilizing investment, and enhancing the region’s security and competitiveness across energy, transport, and digital sectors.

  • 3SI is a cooperation platform of EU member states between the Baltic, Adriatic and Black Seas. It strengthens North–South connectivity in three domains — Energy, Transport, Digital — and convenes governments, business and finance to turn cross-border plans into investable projects.
  • TSBC (Three Seas Business Council) is an independent business hub for regional cooperation among private enterprises, public institutions, civil society organisations and regulators. It acts as a collaboration hub and single strategic gateway — promoting investment, engaging stakeholders and aligning capabilities across borders. 

13 EU states: Austria, Bulgaria, Croatia, Czechia, Estonia, Greece, Hungary, Latvia, Lithuania, Poland, Romania, Slovakia, Slovenia.

Associated Participating States: Ukraine and Moldova (since 2023), Albania and Montenegro (since 2025).
Strategic Partners: the United States, Japan, Germany, the European Commission; since 2025 also Spain and Türkiye.

No. 3SI membership is limited to EU member states. Non-EU countries may engage as Associated Participating States—currently Ukraine and the Republic of Moldova, and since April 2025 also Albania and Montenegro. Serbia is not a member.
Strategic Partners are the United States, Japan, Germany and the European Commission, (since 2024); Spain and Türkiye joined as strategic partners in 2025.
