evidence: To this day, both countries claim ownership over Mali Školj and Veliki Školj, and the tip of the Klek peninsula, which is found nearby. [...] An agreement reached in 1999 deemed that the islands belonged to Bosnia, but Croatia never ratified it. The last attempt at finding a solution took place in 2012, right before Croatia entered the European Union. [...] Serbia and Croatia still haven’t resolved the issue of a portion of their border along the Danube, with another two islands (river ones) caught in the dispute. Croatia claims another disputed peninsula, the Prevlaka, portions of which Montenegro claims as its own because they are found at the entrance of the Montenegrin bay of Kotor. A temporary solution was found in 2012, but negotiations over a long-term agreement have stalled since.
