Main article: Bulgaria-Turkey conflict

The border at the Rezovo's mouth was the subject of a minor territorial dispute between Bulgaria and Turkey, which was settled in the 1990s. As a result of an agreement between the two countries of 6 May 1992 (ratified by Bulgaria in 1998), Bulgaria received a small land area of several square kilometres in the Rezovo Bay in return for water area in the continental shelf.
