Kosor said on Tuesday that the conclusion of the negotiations, which she described as a historic goal, was now a matter of days.
Kosor said that the Fisheries negotiating area, which was closed on Monday, was one of the particularly tough and complicated policy areas in Croatia's membership talks with the European Union.
With the closing of the policy area No. 13, Fisheries, Croatia has four policy chapters left to close: Chapter 23 - Judiciary and Fundamental Rights, Chapter 8 - Competition Policy, Chapter 33 - Finance and Budgetary Provisions, and Chapter 35 - Other Issues.
The premier said that another two difficult areas, Judiciary and Fundamental Rights and Competition Policy, were also about to be closed.
She told reporters that Croatia should continue working hard and with commitment also after the conclusion of the entry talks until the signing of the accession treaty.
Kosor expressed satisfaction with the report which the Hague tribunal's chief prosecutor Serge Brammertz delivered to the UN Security Council on Monday about Croatia's cooperation with the International Criminal Tribunal for the former Yugoslavia (ICTY). She said that Brammertz's report confirmed Croatia's full cooperation with that UN court.
