Congress, have indicated strong backing for the 3SI. In
October 2019, a resolution was introduced in the House of
Representatives “expressing support of the Three Seas
Initiative in its efforts to increase energy independence and
infrastructure connectivity thereby strengthening the United
States and European national security” (H.Res. 672). In
February 2020, U.S. Secretary of State Mike Pompeo
announced a U.S. commitment of up to $1 billion in
financing for 3SI countries to promote energy security and
economic growth.
Initiative Overview
The Three Seas Initiative was launched in 2015 by the
presidents of Croatia and Poland, and the first annual
summit was held in 2016. The 3SI is structured as a flexible
platform for generating funding and promoting deeper
cooperation among its participating countries; one
overarching goal is to develop a north-south infrastructure
corridor in the region. In part as a legacy of the Soviet
Union’s Cold War-era dominance over most of the region,
east-west infrastructure remains considerably more
developed than north-south linkages. Particularly with
regard to energy security, the dominance of east-west
pipelines and limited alternatives to them have been factors
