BRUSSELS, Muharram 8, 1433, Dec 3, 2011, SPA -- A key new agreement on disputed border crossings between Serbia and Kosovo will help quiet objections to Serbia's candidacy for European Union membership, AP quoted the country's chief negotiator as saying Saturday. The accord struck on Friday creates joint border crossing controls in northern Kosovo to be shared by Serb and Kosovo authorities. For months, Kosovo's minority Serbs have blocked roads and battled with authorities in the tense region to reject attempts by the Kosovo government to impose its authority. The EU is divided on on whether to grant Serbia the status of candidate for membership, but German Chancellor Angela Merkel has said that recent clashes at the border between Serb nationalists and NATO peacekeepers in which 50 troops were injured showed that Serbia had not yet fulfilled the proper conditions. The latest deal could significantly ease tensions by establishing joint border control posts comprising Serb, Kosovar and EU police and customs officials. Serb negotiator Borko Stefanovic said the agreement was the thorniest issue in talks between Kosovo and Serbia, which has refused to accept its former province's 2008 declaration of independence. "Serbia's position has been strengthened because it demonstrated its readiness to engage in dialogue and resolve the most difficult questions before us," he said. Government leaders are scheduled to discuss the expansion of the 27-member EU at their forthcoming summit on Thursday and Friday. --SPA 20:05 LOCAL TIME 17:05 GMT www.spa.gov.sa/949069
