Friday's meeting in Kiseljak was the first meeting of Bosnian Croat parties dedicated to changes to the constitution adopted in Dayton in 1995, following a statement recently signed in Washington in which eight Bosnian parliamentary parties supported constitutional reforms.
The Washington statement was also signed by the Croatian Democratic Union of Bosnia and Herzegovina (HDZ BH) and the Croatian People's Union of Bosnia and Herzegovina.
Croatian President Stjepan Mesic forwarded a letter to the Kiseljak meeting, in which he apologised for not being able to accept the invitation to attend.
President Mesic supports all efforts aimed at promoting, protecting and exercising the rights of the Bosnian Croat people, as well as efforts aimed at transforming Bosnia into a functioning state organised in accordance with European standards and criteria, read the letter.
The leader of the Croatian People's Union and the meeting's host, Milenko Brkic, urged adopting an entirely new constitution which would abolish the existing two entities as this solution was the most unfavourable for the Croats.
Some participants in the meeting also suggested constitutional changes which would establish a third entity, although the majority resolutely opposed that.
HDZ BH leader Dragan Covic said the two-entity structure was unacceptable for the survival of Bosnia and Herzegovina and its Croat people.
State Presidency chairman Ivo Miro Jovic said Russia was against any changes to the Dayton agreement.
Also mentioned was a recent motion by the Bosnian Bishops' Conference to replace the current two entities with four regions in which each of the three constituent peoples would have a guaranteed 30 per cent share in the authorities.
The president of the Croatian cultural society Napredak, Franjo Topic, complained that no politicians in either Bosnia or Croatia advocated a greater return of Croat refugees to the Posavina region in the north.
The Bosnian Croat political parties are next scheduled to meet in Mostar in mid-January.
