All the parties but HDZ BiH signed a declaration on constitutional changes, calling for "a comprehensive constitutional reform."
The declaration says that constitutional changes "in addition to the reform of central government institutions in Bosnia-Herzegovina should also provide for new administrative-territorial organisation of Bosnia-Herzegovina."
The Bosnian Croat parties demanded guarantees that their vital national interests would be protected in the upper house of the state parliament.
"Constitutional changes should be adopted institutionally in the Parliamentary Assembly of Bosnia-Herzegovina without one ethnic group abusing its majority status over other groups and without pressure, but through a political consensus reached by all three constituent ethnic groups," the declaration says.
HDZ BiH secretary-general Nevenko Herceg, who attended the meeting, said that his party neither rejected nor accepted the declaration and that it would take a stand on it after it was analysed by party bodies.
This party, led by Dragan Covic, was the only Croat party to support the package of reforms agreed through the mediation of international diplomats, but the previous parliament failed to adopt them this spring.
HDZ 1990 leader Bozo Ljubic said that the declaration would be sent to the newly-appointed Croat member of the country's tripartite Presidency, Zeljko Komsic.
"The declaration will be a test for Komsic and will show to what extent he will be able to function as the representative of the Croat people on the BiH Presidency," Ljubic said.
Komsic was elected as a candidate of the Social Democratic Party.
