Speaking to the press after the meeting, Sanader said all parliamentary parties agreed with the government's proposal to settle the sea border issue with Slovenia through international arbitration.
Sanader said Croatia and Slovenia had only a few outstanding issues and much in common. He added he would suggest international arbitration, in which each side would beforehand commit to agreeing to the mediator's opinion, to Slovene PM Janez Jansa.
Speaking of relations with the EU, Sanader said he no longer wanted to announce the start of the accession negotiations. He added Croatia already shared European values and that it would confirm them through the negotiations and full membership of the Union.
"We are aware that if we want to join a club we must meet the conditions set before new members, but we also know that we can solve every problem and that Croatia's place is in the European Union."
Sanader said he recently informed European officials of the "good implementation" of the Action Plan intended to achieve full cooperation with the Hague war crimes tribunal, which is the condition to open the entry negotiations.
Sanader added that everything said at international meetings had been well-received, as had talks with the Croatian Opposition, which he said shared the government's moderate optimism.
Ivica Racan, leader of the Social Democrats (SDP), the strongest opposition party, told the press they were informed of the Croatia-EU situation and the latest events in relations with Slovenia. He added there had been no talk of the Action Plan because that was a government issue.
Asked if he believed Croatia would start the EU entry talks soon, Racan said he was an optimist but that reality was somewhat different.
He added he had proposed settling the border dispute with Slovenia with international arbitration three years ago, when the first attempt to reach an agreement failed.
Today's meeting was also attended by Foreign Affairs and European Integration Minister Kolinda Grabar-Kitarovic.
