The note by the Slovene foreign ministry says that Croatia was unilaterally encroaching upon the sea, the sea-bed and the subsoil of the former Yugoslav federation which have not been consensually divided among the former republics and part of which belongs to Slovenia, the daily reported.
Ljubljana claims that this is contrary to a joint statement of the two governments from a session held on the island of Brijuni in June 2005 concerning the areas of the undivided sea, sea-bed and subsoil of the former Yugoslavia, the daily said.
The daily also reports that the Croatian foreign ministry understands the Slovene note as insistence that the Adriatic should be further divided.
The ministry believes that such interpretation of international law in unacceptable because it disregards the UN convention on the law of the sea, the daily said.
According to the daily, the former Socialist Republic of Yugoslavia and Italy had concluded an agreement on the demarcation of that part of the Adriatic. In 2005 it was announced that Croatia and Italy had defined co-ordinates in detail regarding the continental shelf.
