"This will be a true European border, open for friends, people, goods and capital, closed for crime, any act of aggression, everything that is not part of the European tradition and European values," said Krivokapic.
He added Debeli Brijeg carried a special lesson for Montenegro. "The lesson that it must know where its border is, that it must never again seize for what does not belong to it and that it will never again let others decide on its behalf."
The construction of the EUR2.5 million border crossing was financed by the European Agency for Reconstruction and the Montenegrin government.
The first border crossing at Debeli Brijeg was opened in 1999. Last year more than 800,000 people passed through it.
