Obradovic-Mazal said there was no area in which the region's countries could not help one another, notably in the sharing of experience in the meeting of criteria on which the EU insists.
The chief of the Serbian government's Office for Association with the EU, Tanja Miscevic, and Montenegro's Minister for International Economic Relations and European Integration, Gordana Djurovic, also supported the need to further strengthen regional cooperation on the road to the EU.
The chief of the EU delegation to Bosnia and Herzegovina, Michael Humphreys, underlined the need to intensify communication in the region, recalling that the Union was created on such foundations as well.
