Dzurinda's statement was quoted in the Wednesday edition of the Slovak English-language newspaper, The Slovak Spectator.
Since Prime Ministers Ferenc Gyurcsany of Hungary, Jiri Paroubek of the Czech Republic, Marek Belka of Poland and Dzurinda failed to agree on how much progress Croatia had made, they decided not to send a formal letter to British Prime Minister Tony Blair, whose country currently holds the EU rotating presidency, and European Commission President Jose Manuel Barroso, urging the EU to open membership talks with Croatia, the newspaper said on its website.
The Hungarian prime minister, however, said that his country would send a letter supporting the opening of entry talks with Croatia.
During his visit to Slovakia in March, Croatian Prime Minister Ivo Sanader received assurances from his Slovak counterpart that Slovakia would continue to support Croatia's EU membership bid.
Dzurinda is one of the most active supporters of Croatia, the newspaper said.
