The Reuters agency quoted Asselborn as saying on Wednesday that "Croatia still had a week to show it was doing its best and the decision by EU foreign ministers on March 16 would be a political one."
"I could imagine that a situation could arise in which Croatia can prove by March 16 that its cooperation is 100 percent without it perhaps being possible up to that point to transfer Gotovina to the Hague," Asselborn told Deutschlandfunk radio in an interview, according to Reuters.
Asselborn said the key to the decision lay neither with Del Ponte nor with the EU foreign ministers but in Zagreb.
"The Croatian government is doing a great deal at the moment to prove its 100 percent cooperation. But the evidence is still lacking. Gotovina has not always been regarded as a criminal and is not seen even today by many people in his country as a criminal," the Luxembourg minister was quoted by Reuters as saying.
