Summary

On or about 22 May 2024, Russia, via a Defense Ministry-prepared document and Cabinet of Ministers resolution annex, declared intentions to unilaterally move its maritime border with Lithuania and Finland in the Baltic Sea. Russia aims to assert parts of the water area east of the Gulf of Finland, near the cities of Baltiysk and Zelenogradsk in Kaliningrad, as its internal sea waters. Specific coordinate adjustments are planned around Finnish border islands including Jähi, Sommers, Holland, Rodsher, Maly Tyuters, Vigrund, and near the Narva River's northern entrance cape. On Lithuania's border, adjustments target the Curonian Spit, Cape Taran, and the Baltic Spit. This move constitutes a significant geopolitical and territorial assertion in strategically sensitive maritime zones.
