"In Europe there is a serious problem given that 25 member states, namely 27 when Romania and Bulgaria join the bloc, have to agree about the EU Constitution," Sanader said on Monday during his visit to the northern Croatian county of Medjimurje.
He said this while responding to questions by reporters who covered his visit to the town of Gorican.
Over the weekend EU foreign ministers who convened in Klosterneuburg, outside Vienna, agreed that 2009 would be a year of key importance for the European Constitution, and in this way they prolonged "a period of reflexion" which was proclaimed a year ago after a majority of the French and the Dutch rejected the draft of the EU Constitution at referendums in their respective countries.
"I am sure that the EU will soon solve this issue and before the deadline it set for (2009)," the Croatian premier said today.
He added that regardless of the process of the adoption of the Constitution in EU member states, Croatia had a possibility for being admitted to the EU as the 28th member in accordance to amendments to the Nice Treaty.
The 2001 Treaty of Nice includes agreement on capping the size of the EU at 27 members.
According to Sanader, if there are no possibilities for his country, Croatia would not have opened membership talks with Brussels.
"For Croatia it is of vital importance to complete the negotiations in a high-quality manner and to find good solutions. After that it is only a technical issue how Croatia will enter the EU," he explained.
