Sanader, who gave an interview with the television's prime time news programme, stressed that he continued to be optimistic.
According to him, in the coming period, Croatia is going to intensify dialogue with EU member-countries that do not think that Croatia is fully cooperating with the Hague-based UN war crimes tribunal, so as to persuade them in the opposite.
Contacts will be intensified also with the Luxembourg presidency over the EU and with the ICTY tribunal.
Sanader said that he would try to raise again the issue of the opening of Croatia's entry talks next week at a meeting of leaders of the European People's Party (EPP).
"Of course I cannot be satisfied with the fact that the talks will not start tomorrow, but I am not disappointed," Sanader said.
He said he was especially satisfied with the fact that the EU Council of Ministers today adopted a negotiating framework with Croatia in which it stated that the aim of the talks was Croatia's full membership in the Union.
In this way, a possibility of a joint scenario with another country-candidate has been avoided, and now it is not theoretically possible for Croatia to be in the same package with it, he added.
