"It is absolutely certain that people who left Yugoslavia, and we know how it happened, do not consider rejoining it or anything that would resemble it," the president of Croatia's strongest opposition party said in an interview on national television on Tuesday evening.
Racan said he could not imagine the European Union forcing Croatia into such an association and abandoning the principle of an individual approach to the EU at the expense of a regional approach.
"Croatia would be punished that way, and I think none of us would want to join such an EU, and should that happen I would automatically become Euro-sceptical," he said.
Racan said he supported Prime Minister Ivo Sanader in his efforts to modify the EU's initiative by proposing expansion of the Central European Free Trade Agreement (CEFTA).
He also supported a Council of Europe resolution condemning communist crimes.
