Answering questions from reporters during her visit to Rovinj on Monday, Kosor ruled out the possible engagement of the IMF.
She dismissed media speculations that indecisiveness in implementing reforms would force Croatia to turn to the IMF for assistance.
"We don't need anyone. I think we in Croatia, primarily the government, together with leaders of local communities, absolutely can and must carry out the economic recovery programme," Kosor said.
Recalling that the government's bail-out programme was supported by the World Bank and the IMF and leading economists in Croatia, the premier said its implementation required "a little more strength and resolve from everybody," including the trade unions and the employers.
