"He promised me support in connection with the setting of the date for the start of negotiations with the EU," Sanader said.
This was the third meeting between the prime ministers of Croatia and Greece which, Sanader said, have no outstanding issues.
The two officials also talked about the Adriatic-Ionian Highway Project. Sanader said both countries were interested in the project, and that construction in Croatia was proceeding well.
Sanader visited Thessaloniki to attend the eighth dialogue between the Orthodox Church and European People's Parties (Christian Democrats), which focused on reconciliation and cooperation among the peoples of Southeast Europe.
The event pooled representatives of the Association of the European People's Party (EPP) and European Democrats, senior religious dignitaries, Sanader, Karamanlis, and Serbian PM Vojislav Kostunica.
Although their attendance was announced, Zagreb Archbishop Cardinal Josip Bozanic and representatives of Bosnia-Herzegovina's Party of Democratic Progress and Party of Democratic Action did not attend.
Barisa Colak, president of Bosnia's Croatian Democratic Union, said in his speech at the event his party had always advocated sovereignty and all national and political rights for all peoples, including Bosnian Croats. He added that Croats in Bosnia, however, did not enjoy said rights fully and equally.
Colak asked for the exercising of the right of all displaced persons to return to prewar homes, the rights to their own language, to education in Croatian, and to Croatian-language media.
In his address, EPP president Wilfred Martens called on Croatia, Serbia and Montenegro, Bosnia-Herzegovina, Macedonia as well as Slovenia to hold talks about reconciliation and cooperation.
After the Thessaloniki meeting, Sanader departed for Bucharest, where on Friday he is attending a ministerial meeting of countries of the Southeast European Cooperation Process. He is due to sign a regional cooperation charter.
