Next Balkan crisis: Kosovo bans Serbian currency - West reacts with concern. Serbia and Kosovo have just settled their long-standing bitter dispute over license plates, and the next crisis is already looming.

From Thursday, only the official currency, the euro, will be accepted in the former Serbian province. The Serbian dinar, which was previously tolerated in the regions inhabited by the majority of the Serb minority, will thus be banned. Belgrade did not recognize Kosovo's declaration of independence in 2008 and continues to consider it its province.
