The European Union has renewed criticism of Croatia for not making enough progress in co-operating with the Hague war crimes tribunal.
Ante Gotovina still has supporters in Croatia
Co-operation with the United Nations court is a condition for the start of EU accession talks.
A spokeswoman for Chief UN Prosecutor Carla del Ponte said the EU position would not change unless war crimes fugitive Ante Gotovina was arrested.
Failure to do so has already delayed the talks, initially planned for March.
Gen Gotovina is wanted for alleged war crimes against ethnic Serbs in 1995.
A report by Ms del Ponte was due to be presented to the UN Security Council next week.
The EU's enlargement commissioner, Ollie Rehn, said the chief prosecutor had shown that some progress had been made, "but for the time being co-operation cannot be described as full".
"I regret that this is the case, but I understand that the Croatian authorities need more time to ensure that democratic structures are fully in control and that the entire state administration complies with the rule of law and with international obligations," Mr Rehn said in a statement.
"The EU is ready to start accession negotiations, as soon as Croatia meets the conditions."
Zagreb has said Gen Gotovina is no longer in Croatia.
Meanwhile justice ministers from Croatia, Serbia and Bosnia are meeting to discuss co-operation in prosecuting war criminals.
