Sanader has convened such a meeting for Thursday to consider the current political situation within the context of Croatia's EU integration.
Racan said on Wednesday problems could not be solved with one meeting, but with good practice and conduct by the executive authority.
He maintains that the biggest hurdle to Croatia's EU integration is not fugitive general Ante Gotovina, who is wanted by the UN war crimes tribunal in The Hague, but the political situation at home, the scandals and conflicts he said the authorities solved only "under duress".
He declined to give an explicit answer to the question from the press whether Sanader should resign if it was proved that he knew that secret services had been monitoring the President of the Republic.
"One can't talk about that easily and without facts," he said, adding that if proved true it would be a serious issue. He said Watergate would be nothing compared to this if this proved to be true.
He resolutely refuted allegations that he and Sanader agreed that Parliament should scrap the initiatives to set up commissions of inquiry into former and current senior officials' business activities.
Racan recalled that he had already urged stopping the war with the commissions of inquiry, but said the issues they were expected to address should not be swept under the carpet.
