"Slovenia rejects arbitration that would cover only the sea border. Our opinion is: if no agreement has been reached, then it is necessary to start talks on the entire border, or rather on all points in dispute," Rupel said in a Slovene television current affairs programme on Tuesday evening.
Rupel said that he was somewhat surprised by the letter although it contained nothing new, adding that Croatia, by proposing arbitration only on the sea border, "wants to capitalise on previous negotiations and agreements."
He noted that the Drnovsek-Racan agreement of 2001 was well-balanced and that based on that document Croatia made certain concessions regarding delimitation on the sea, while Slovenia acquiesced regarding several hamlets south of the Dragonja river.
"Croatia now wants to pocket what we agreed then regarding the land border and open the issue of the sea border. That, of course, is unacceptable," the Slovene foreign minister said.
