But negotiations were suspended a year ago following the Serbian government's failure to arrest and hand over former Bosnian Serb military commander Ratko Mladic to the International Criminal Tribunal for the former Yugoslavia (ICTY) by April 30th, 2006, as Kostunica had promised.
Međutim, pregovori su prekinuti prije godinu dana zbog neuspjeha srbijanske vlade da uhiti i izruči vojnog zapovjednika bosanskih Srba Ratka Mladića Međunarodnom kaznenom tribunalu za bivšu Jugoslaviju (ICTY) do 30. travnja 2006, kao što je Koštunica obećao.
