In an interview for Mostar-based Danas weekly, Pack said cooperation with the International Criminal Tribunal for the former Yugoslavia (ICTY) was a condition which every country in the region had to meet before starting entry talks.
"From my point of view, in this area Croatia has done all it could and now it is up to General Ante Gotovina, who also holds a French passport and can be anywhere, to do what he should for the future of his country and surrender himself," Pack said.
General Gotovina has been on the run since July 2001 when the UN war crimes tribunal unsealed his indictment.
The German parliamentarian also called on Croat politicians in Bosnia-Herzegovina to work to improve the position of Croats in Banja Luka (north-western area) and in Bosnian Posavina (northern area).
Croat politicians should not be interested only in Herzegovina (southern area), she said and added that they should also focus on other Bosnian areas where Croats live," she added.
