20 July 2011 Kosovo banned all imports from Serbia and introduced 10 percent tax for imports from Bosnia as both countries blocked exports from Kosovo. On 26 July 2011, a series of confrontations in North Kosovo began with a Kosovo Police operation to seize two border outposts along the Kosovo Serbia border and consequent clashes continued until 23 November. The clashes, resulting in multiple deaths and injuries, were over differences between who would administer the border crossings between Kosovo and Serbia along with what would happen with the revenue collected from the customs and removal of roadblocks to secure freedom of movement. On 3 September 2011, a deal to unblock the impasse between Serbia and Kosovo over exports was struck at EU-led negotiations in Brussels. Serbia agreed to accept goods marked “Kosovo Customs”, while Pristina gave up including state emblems, coats of arms, flags, or use of the word “republic” allowing Kosovo to interpret the label as referring to the customs of independent Kosovo, whereas Serbia could see it as a provincial customs label.
