In an interview with Montenegro's Monitor weekly, which hit newsstands on Thursday, Marovic said it was important for the referendum's result not to endanger Montenegro's stability.
Speaking of possible talks on the separation of Serbia and Montenegro, Marovic said the reaching of an agreement to that effect would require the consent of both Brussels and Belgrade.
He cautioned that Montenegro must not expose itself to the danger of unilateral moves which would be contrary to the spirit of the Belgrade Agreement, and added he believed nobody in Montenegro wanted the referendum to be held in an atmosphere of political hostility and latent conflicts.
The Belgrade Agreement reached between Serbia and Montenegro envisages that three years after the establishment of the state union, one of the two members may hold a referendum on its territory to poll citizens as to which and what kind of state they want to live in.
Speaking of elections for the state union parliament which under the Constitution should be held early next year, Marovic said he hoped Belgrade and Podgorica would be able to harmonise views, with assistance from Brussels, as to when and how the polls would be held.
He said he expected everyone to act responsibly, adding that in talks with European Union representatives he pointed to the importance and possible problems of democratic elections for the state union parliament.
Montenegro would like the elections to be held after the referendum, which is expected to be held next year, whereas Belgrade believes they should be scheduled by the end of this year.
