Why in the news?

During the Raisina Dialogue 2026 in New Delhi, Sibi George, Secretary (West), MEA, met Ambassador Romana Vlahutin, Special Envoy for 3SI, to discuss strengthening connectivity and infrastructure for trade and investment.

Three Seas Initiative (3SI) Background 

Three Seas Initiative  (3SI) was proposed in 2015 by Kolinda Grabar-Kitarovic (President of Croatia) and Andrzej Duda (President of Poland), inspired by a report from the Atlantic Council that highlighted the investment gap in Central and Eastern Europe. 

The first summit was held in 2016 in Dubrovnik, Croatia, and since then, annual Three Seas Summits and Business Forums have taken place, rotating among member countries.
