During his first trip to Brussels as prime minister, Kostunica initially proposed the creation of Serb cantons in Kosovo as a way of preventing a repeat of fierce clashes between Serbs and Albanians in the province.
Tokom prve posete Briselu u svojstvu predsednika Vlade Srbije, Koštunica je prvobitno predložio stvaranje srpskih kantona na Kosovu, kao način da se spreče novi žestoki obračuni između Srba i Albanaca u pokrajini.
