BELGRADE, June 2 (Xinhua) -- The European Union (EU) supports "a constructive break-up" of Serbia-Montenegro as the loose state union was unsustainable, EU foreign policy chief Javier Solana said in Belgrade on Friday.

    Solana, who made his first visit to Belgrade after Montenegro'sindependence referendum, told the press that the union between Serbia and Montenegro lost momentum although the EU has invested much energy in bringing the two republics together.

    With the help of Solana, Serbia-Montenegro was established in February 2003 to succeed the Federal Republic of Yugoslavia. The two republics are entitled to hold independence referendum three years later, according to the Belgrade Agreement.

    In the May 21 referendum, 55.5 percent of turnout voters supported Montenegro's independence from the union with Serbia, surpassing the threshold of 55 percent mediated by the EU. Montenegrin parliament Speaker Ranko Krivokapic has said that the parliament would convene on June 3 to proclaim the independence ofMontenegro.

    Solana said that Serbia and Montenegro should conduct dialogue as soon as possible to resolve numerous political and technical issues.

    Following talks with Solana, Serbian Prime Minister Vojislav Kostunica said that all problems between Belgrade and Podgorica could be resolved via a direct dialogue and Brussels' help is not needed.

    "Matters are quite clear. Serbia is the successor of the state union of Serbia-Montenegro and the Serbian parliament will shortlyconfirm this," Kostunica said.

    Addressing the press after meeting Serbian President Boris Tadic, Solana said that Serbia's links with Montenegro should be constructive.

    "Serbia wants the best possible relations with Montenegro, thuscontributing to its own interests, stability in the region and Europe," Tadic said. Enditem
