Germany and Sweden established their Baltic Sea continental shelf boundary in 1978. It is composed of two straight lines which extend for 29 nautical miles, spanning between Danish maritime spaces in both the east (Bornholm), and the west (Sjaelland). The Germany– Sweden boundary line has never been considered controversial, and the 1978 Agreement served to formalize the States’ previous understanding of maritime claims in the region. In addition to defining the official maritime boundary, the Treaty also expressed the Parties’ joint concern for the utilization of environmental resources. To that end, the Parties agreed in a separate protocol, signed on the same day, that the continental shelf boundary would also serve to define the fishing zones between the two States.
