"There is no reason for pessimism or the slowing down of talks which are gaining momentum and content under the Finnish presidency," Drobnjak told Hina on the phone.
"It is encouraging that member-countries have already drawn up a time plan for the drawing up of a new institutional framework," Drobnjak said.
The EU is functioning according to the Nice Accord, which was designed for 27 member-states. The Nice Accord should be replaced with the first European constitution, but the ratification of the constitution came to a halt after the constitution was rejected at last year's referendums in France and the Netherlands.
Drobnjak explained that agreement was reached to draw up a new constitutional framework during the German presidency of the EU in the first half of 2007 and to adopted it by the end of 2008 at the latest, during the French presidency.
This is enough time to find a solution for Croatia as well, he said.
"The most important thing for Croatia at the moment is to successfully continue negotiations, and as Croatia makes progress with the talks and opens new chapters and provisionally closes them, its position will become stronger, as will its chance of finding a good place in the new institutional framework," Drobnjak said.
