The Neum Agreement is an unimplemented treaty between Croatia and Bosnia and Herzegovina granting free passage of transit traffic between the territory of Dubrovnik-Neretva County around the city of Dubrovnik and forming a pene-exclave of Croatia and the reaining Croatian territory through the municipality of Neum.
The agreement was signed in Zagreb, Croatia on 22 November 1998 and followed by a protocol of 11 December 2001 further regulating the issue. The agreement provides for unobstructed transit of vehicles with Croatian license plates and documents traveling from and to Croatian territory, prohibits loading or unloading of goods or passengers and changes of mode of transportation except in cases of traffic accidents or vehicle breakdowns, but it does allow officials of the Bosnia and Herzegovina to prohibit transit of goods whose import is not permitted due to health concerns. The agreement finally provides that it shall be in force as long as Ploče Agreement, regulating use of the Port of Ploče by Bosnia and Herzegovina, is implemented.
As of 2012[update], the treaty is still not ratified (it was not published in Narodne novine) and there is no actual route permitting the type of transit provided for by the agreement where vehicles would not stop for border controls in the area. At the time Klek/Neum 1 and Neum 2/Zaton Doli border crossings on the D8 state road are available to international road traffic, along with Vukov Klanac and Imotica border checkpoints which are available for local traffic only.
