"As far as I'm aware, the government has done its best to establish the whereabouts of the documents (sought by the tribunal) and to find them. If the (tribunal's chief) prosecutor thinks that more should be done, we will gladly do so. I believe that Croatia will continue to work on finding the documents and establishing what happened with them," Josipovic said, adding that Croatia had done very much so far.

When asked if more would be known about the opening of the negotiation chapter on judiciary in Croatia's EU entry talks after a regional conference of state prosecutors' offices, to be held on the northern Adriatic archipelago of Brijuni on Thursday and Friday, Josipovic said this issue depended on EU member-countries and Croatia's talks with each member-country.

"State prosecutors' offices from Croatia, Serbia, Montenegro and Bosnia and Herzegovina have started cooperating very seriously, there are very good results, and I think that all factors have already commended that cooperation," Josipovic said when asked to comment on the statement by the Hague tribunal's chief prosecutor, Serge Brammertz, that the most important thing at the moment was to strengthen cooperation of the state prosecutors' offices of Croatia, Serbia, Montenegro and Bosnia and Herzegovina with the Hague tribunal, and their cooperation with one another.
