Klek peninsula is a territory of Croatia
After the Badinter Commission Yugoslavia was decided to enter "in process of the dissolution", the first boundary agreement between successor states has been achieved. The Treaty on the State Border between Republic of Croatia and Bosnia and Herzegovina was signed by the Croatian President, Franjo Tuđman and Alija Izetbegović, who was the member of the Presidency of Bosnia and Herzegovina in 1999. The agreement was signed on 30 July 1999 in Sarajevo. The state border between the countries is determined according to the borders at the end of Socialist Federal Republic of Yugoslavia in 1991. The sea border in the area of Neum and Klek peninsula is delimitated by way of an equidistance line. (see figure 1 below). Article 4 of the treaty states that the State border on the sea stretches along the central line of the sea between the territories of the Republic of Croatia and Bosnia and Herzegovina in accordance with the 1982 UN Convention on the Law of the Sea.[12] It is important to consider that both small islands near the Klek peninsula which are Mali Školj and Veliki Školj are given to BiH as well since they are so close to Klek peninsula.
