Bosnia and Herzegovina and Croatia agreed on a border demarcation treaty in 1999. The treaty was signed by the two former presidents, Alija Izetbegović and Franjo Tuđman, but it was never ratified by the respective parliaments so, therefore, it had never entered into force. The agreement foresees a definition of the two countries' territory, in the area of the Pelješac peninsula which is slightly different from what is shown on maps, since Croatia agreed to recognise the sovereignty of Bosnia and Herzegovina over two small rock islands (Mali Školj and Veliki Školj) and the tip of the peninsula of Klek near Neum.
