In its present situation, in the process of the ratification of its EU Accession Treaty and ahead of its EU entry, Croatia should be very careful about its credibility, Tuerks said.

Tuerks said that when it came to the Ljubljanska Bank issue and old foreign currency deposits, Croatia should respect previously agreed obligations, adding that in that context, statements made by the Croatian government recently were surprising and made one question Croatia's credibility.

The Prime Ministers of Croatia and Slovenia, Zoran Milanovic and Janez Jansa, met in in Maribor earlier this week and said that relations between Slovenia and Croatia were good and they had not been compromised even by the recently reopened issue of Ljubljanska Banka. The two PMs said nothing would change in that respect because both governments honour the obligations taken over by their predecessors.

Milanovic said that a week ago his government withdrew a conclusion on Ljubljanska Banka adopted two to three weeks ago because it was "irrelevant" since it concerned a lawsuit in which the government had no right to interfere.

"The Croatian government in no way changed its position nor did its conclusion imply any change of position," Milanovic said, adding that the conclusion was withdrawn as an act of "good will and good faith".
