Greece has been supporting Croatia in its bid to enter the EU since the very start. But it is always important to cooperate with international courts as this is a condition of international law, and cooperation must be rewarded, Karamanlis said in Zagreb.
Sanader added that he informed his Greek counterpart of Croatia's ambitions to receive the European Union's positive response to the start of Croatia's accession talks on 17 March, as well as about all what the country had done so far to begin the membership talks.
"I expect that the interpretation that Croatia's full cooperation with the ICTY means that Croatia is doing its utmost to solve the last remaining outstanding case in relations with the Hague-based tribunal will prevail in the European Union," Sanader said alluding to the case of the runaway general Ante Gotovina, who is wanted by the tribunal.
Karamanlis said that he purposely selected Zagreb as the first stop in this tour of southeastern European countries.
I have chosen Zagreb from the obvious reason: the promotion of European prospects in the southeastern region is a Greek strategic interest," said Karamanlis.
Croatia is currently the leading country in Southeast Europe when in comes to EuroAtlantic integration processes, the Greek PM said.
The two officials also discussed the situation in the region and bilateral relations.
Sanader and Karamanlis highlighted excellent political relations between Croatia and Greece, expressing hope that they would pave the way to an improvement of economic cooperation between the two countries.
After Zagreb, Karamanlis will travel to Belgrade to meet Serbian President Boris Tadic and Montenegrin Prime Minister Milo Djukanovic. On Thursday, the Greek PM will meet his Serbian counterpart, Vojislav Kostunica, and the President of Serbia and Montenegro, Svetozar Marovic. He will then proceed to Pristina.
