"As I announced two days ago, Croatia presented its position. We fully accepted Commissioner Rehn's final compromise proposal. Slovenia presented its position and adopted amendments which are unacceptable to Croatia. Commissioner Rehn took note of that and will brief the presidential troika," Jandrokovic said after a meeting with Rehn and Slovene Foreign Minister Samuel Zbogar.
The troika, comprised of the European Union's previous, current and next presidents -- France, the Czech Republic and Sweden -- is expected to meet in the week following elections for the European Parliament, which end on June 7, and before the next regular meeting of the Union's foreign ministers in Luxembourg on June 15.
Rehn's spokeswoman Krisztina Nagy briefly said the commissioner had taken note of Slovenia's and Croatia's responses to his final compromise proposal.
The commissioner welcomes the two countries' commitment to the EC's facilitation process, which has been endorsed by the presidential troika and the EU member countries, she said, adding that Rehn would soon brief the presidential troika with a view to concluding the process.
Although Rehn's statement shows his intention to finish his mediation soon, Slovenia's Minister Zbogar said that the process was half way through.
"Commissioner Rehn heard both sides, and he will take some time for consideration and for talks with the presidential troika on how to move forward. We agreed to resume talks in the first half of June. We will meet again to talk and try to draft an agreement," Zbogar told Slovenian reporters in Brussels.
He added that his next meeting with Rehn and Jandrokovic would be held after a meeting of the EU presidential troika.
According to Zbogar, Rehn's latest compromise proposal was not on a take-it-or-leave-it basis and Rehn was willing to accept minor changes.
On 8 May, Croatia agreed to Rehn's proposal on the resolution of its border row with Slovenia, which has been blocking Zagreb's EU accession talks for months.
Later in May, Slovenia sent its amendments to the commissioner's plan for solving the row and lifting Slovenia's blockade of Croatia's EU membership talks.
On 22 April, Commissioner Rehn proposed that an ad hoc arbitration court be engaged in efforts to solve the two countries' border dispute.
A five-member arbitration tribunal would define the border on land and at sea in compliance with international law. The use of maritime areas by Slovenia and Slovenia's contact with the open seas would be regulated in accordance with international law, the principle of equity and in the spirit of good neighbourliness.
The proposal put forward by Rehn is backed by the EU presidential troika (France, the Czech Republic and Sweden) and EU foreign ministers.
