Describing the European integration processes as a millennial enterprise, Mesic said that upon its unification Europe will become the greatest factor of peace in the world.
"In its past Europe was united several times but each time through the use of force, that is, in the interest of those who had the force. This time it will be integrated on the basis of the interests of both small and big countries, those less powerful and those more powerful," he said.
"Unfortunately, Slovenia is now halting that process because it believes that negotiations with the European Union can be tied with a bilateral border problem," Mesic said, referring to Ljubljana's vetoing of Croatia's EU membership talks due to their border row.
"If we strive for the rule of law in our country, in global relations we must also strive for the rule of law among internationally recognised subjects," Mesic said, adding that therefore international law must be applied in solving the border dispute.
"It is unacceptable that certain politicians demarcate borderlines," he said.
