Maritime Delimitation in the Baltic Sea: An Update

Research output: Contribution to journalArticle


The present contribution is a follow-up to an article published in the same journal about a decade ago on the accomplishments by coastal States in the restricted area of the Baltic Sea with respect to the delimitation of their different maritime zones [6]. The research on which both contributions are based is related to the work accomplished by the present author in the framework of a world-wide project initiated by the American Society of International Law during the late 1980s, which intended to provide an in-depth analysis of the State practice arising from the more than 100 existing maritime boundary delimitation agreements already concluded at that time. That project is still on-going and finds its reflection in the publication “International Maritime Boundaries”, of which eight volumes have seen the light of day so far, the latest one in 2020.1 In this follow-up article three new agreements have to be mentioned. It concerns, in chronological order of signature, the tripoint agreement concluded between Lithuania, Russia and Sweden of 2005,2 the agreement between Lithuania and Sweden of 2014,3 and the Denmark-Poland agreement of 2018.4 All of these agreements have in the meantime entered into force5 and will form the central part of the present contribution (Part II). But in order to be able to understand the exact place of these agreements in the overall maritime delimitation picture of the Baltic Sea, a very broad sketch will first be provided of what preceded these recent three additions (Part I). Both these parts, unless otherwise indicated, rely on previously published material listed in the bibliography either at the end of the article that is being updated concerning Part I, or the more recent works listed at the end of the present contribution concerning Part II. Finally, some conclusions will be drawn (Part III).
