Bosnia and Herzegovina–Croatia relations
The Herzegovinian municipality of Neum in the south makes the southernmost part of Croatia (Dubrovnik–Neretva County) an exclave. In 1999, a border agreement between former Croatian President Franjo Tuđman and President of Bosnia and Herzegovina Alija Izetbegović moved the Croatia – Bosnia and Herzegovina border near Neum from the very coast (during SFR Yugoslavia era and confirmed by the Badinter Arbitration Committee) further into the sea waters of the Mali Ston Bay, placing two Croatian islands (Mali and Veliki Škoj, incidentally translated into English as "Little" and "Big Island") under Bosnia-Herzegovina sovereignty. Six years later, the Croatian government called for the ratification of this agreement; however, as of 2007, it was not ratified. The two countries negotiated Neum Agreement and Ploče Agreement defining special arrangements for Croatian transit traffic through Neum and Bosnia and Herzegovina access to the port of Ploče to compensate for non-contiguity of Croatian territory between Ploče and Dubrovnik and lack of a seaport in Bosnia and Herzegovina.
