Προειδοποίησε ότι αν ακυρωθούν οι προοπτικές των Βαλκανικών χωρών για ένταξη στην ΕΕ, "Η επίλυση των σημαντικών ζητημάτων της περιοχής μας θα είναι πιο δύσκολη".
"Europe will not be complete without the Balkans," Tadic said, adding "The French referendum... does not mean the end of integration but possibly a change of pace." If the Balkan countries' prospects for EU membership were cancelled, "All outstanding issues in our region would be much more difficult to resolve," he warned.
