Two days before Sofia hosts a meeting of the Stability Pact for South Eastern Europe regional table, Bulgaria's Foreign Minister Ivailo Kalfin was uncertain whether it would be attended by any representatives from Kosovo, which declared its independence from Belgrade on February 17 2008.

"There are certain delicate moments, related to protocol, concerning the forthcoming meeting. We are doing everything possible to solve them," Kalfin told reporters on February 25, quoted by Focus news agency.

Serbia's foreign minister Vuk Jeremić was expected to attend the meeting in Sofia, but Kalfin admitted it was unclear who would represent Kosovo and whether it would be present at the meeting at all.

"We want to ensure that everyone can participate fully in our discussions on regional co-operation. It is obvious that there is a lot of tension between Serbia and Kosovo, so we are looking for a framework that would be acceptable to all sides," he added.

However, Kalfin stressed that none of the countries from the region that have rejected Kosovo's independence has objected to the province being represented at the meeting. Romania and Greece are among the countries in the region that have said they would not recognise Kosovo as an independent state.

The one-day regional table in Sofia on February 27 will mark the final meeting of the organisation under the Stability Pact name. From March 1, it would become the Regional Co-operation Council.

Bulgaria, which said it would "establish relations" with Kosovo, is yet to decide whether it would upgrade its diplomatic mission in Prishtina to embassy status, Kalfin added.
