The meeting is scheduled to take place ahead of the tenth anniversary of the Dayton peace accords, which were concluded on 21 November 1995 putting an end to the war in the country.
According to the Bosnian press on Friday, most participants were cautious about expectations of the Brussels meeting.
The British daily Guardian on Thursday reported that local political leaders were expected to take a position on "the draft which, for the first time since the war ended 10 years ago, would give Bosnia the 'normal' trappings of an integrated, non-ethnic parliamentary democracy: a national parliament with full legislative powers, central government and cabinet enjoying full executive power, and a titular head of state."
"The deal, if agreed, would it is hoped help to undo the bitter legacy of the war and the ethnic pogroms that were its main feature and steer the country towards multi-ethnic integration. If successful, it would be a rare triumph for western "nation-building" efforts in 'failed states' and war-ravaged countries," read the article in Thursday's issue of the daily.
Donald Hays, a former US state department official who served for four years in Bosnia as deputy to the High Representative Paddy Ashdown and his predecessor, is the key architect and driver of the plan.
Leading Bosnian politicians, however, said that they had not yet seen any document of that kind.
