The session was also attended by President Stjepan Mesic and Parliament Speaker Vladimir Seks.
Addressing the session, County Prefect Kresimir Bubalo said that the local population was dissatisfied with the situation in the county, which he said for the first time in Croatia's history was the country's poorest region.
"Unbalanced regional development weakens Croatia's strength as a whole, and the best proof of this is the construction of a bridge linking the Peljesac peninsula with the mainland, which definitely cannot be a higher priority than helping Slavonija pull out of poverty," Bubalo said.
Addressing the session, President Mesic said that the county's economy, destroyed in the war and the subsequent privatisation process, could not achieve the desired level of development on its own.
Central bodies of authority, parliamentary deputies and local officials are therefore expected to do more for the development of the county, Mesic said, warning that the criticism of centralism must not result in exclusive regionalism.
"In order to eliminate suspicions about war crimes and establish the individual responsibility of perpetrators... all judicial institutions must do their job," Mesic said, adding that this referred to all cases and not only those that were currently in the focus of public attention.
