Participants were agreed the time of wars and misunderstandings is history and political and economic cooperation the future of Europe's Southeast, without which EU enlargement will not be completed.
The host, Croatian Prime Minister Ivo Sanader, President Stjepan Mesic, and Parliament Speaker Vladimir Seks underlined that Croatia's accession to the EU and NATO was a national priority.
They said Croatia had made great progress in Euro-integration and that Zagreb was willing to help neighbouring countries which are at different degrees of association.
Similar messages could be heard from the other participants, Albanian PM Sali Berisha, Montenegrin PM Milo Djukanovic, Romanian PM Calin Popescu Tariceanu, Bosnia and Herzegovina PM Adnan Terzic, Georgian President Mikhail Saakashvili, several foreign ministers and other senior officials.
However, the leaders of the region's countries were also given warnings to the effect that the integration process envisages stronger engagement in the implementation of set conditions.
Council of Europe Parliamentary Assembly President Rene van der Linden said the countries in the region should be more decisive in reform implementation because EU membership was not automatic and was not the result of geographic position.
I reiterate, carry out your tasks, and then you will receive our assistance, he said.
Assistant US State Secretary Dan Fried commended Croatia for the reforms it carried out and pointed the finger at Serbia, saying it must decide whether it wanted a nationalist past or a European future.
Speaking of Kosovo, Fried said there would be no division or separation of Kosovo, that it would not be annexed to anyone or monoethnic.
