Serbia-Montenegro tensions flare over 20th independence anniversary

Serbian President Aleksandar Vučić has sparked a new diplomatic row with Montenegro by publicly declining an invitation to the country’s upcoming 20th anniversary celebrations of its 2006 independence from Serbia, describing the event as a “glamorous celebration of secession from my Serbia.”

Montenegro rejects Serbia’s narrative that their country separated from Serbia, as Montenegro has never been part of Serbia in history.

Speaking to journalists on Thursday at the construction site of the Expo 2027 exhibition in Belgrade, Vučić said he received the invitation but would not attend. “I love Serbia more than anything in the world, and to celebrate something like this would be shameful. I would spit in my own face and in the face of my people. Let them celebrate whatever they want,” he stated.

He also referenced the scale of the planned events, including a performance by American singer Ricky Martin, framing the anniversary as a lavish commemoration of separation rather than a neutral national holiday.

Montenegro’s Foreign Ministry responded critically to Vučić’s remarks, viewing them as inappropriate and undermining Montenegro’s sovereignty and good-neighborly relations.

In turn, Serbia’s Ministry of Foreign Affairs issued a detailed rebuttal, accusing Montenegro of fabricating a pretext to attack Vučić and engaging in selective historical interpretation.

Serbia’s MFA statement emphasized that Belgrade recognized Montenegro’s independence and territorial integrity immediately in 2006, supports its EU integration, and remains committed to cooperation based on mutual respect. However, it criticized what it sees as Montenegro’s denial of Serbian identity among its citizens and rhetoric that hinders regional progress.

Background and context

Montenegro held a closely contested independence referendum in May 2006, with just over 55% voting to separate from the State Union of Serbia and Montenegro. Serbia formally recognized the result shortly afterward. Despite this, relations have often been strained by issues including the status of ethnic Serbs in Montenegro (who make up a significant portion of the population), language, culture, and competing historical narratives.

The 20th anniversary celebrations are scheduled for 21 May. The episode fits a recurring pattern of friction between the two neighbors, even as both pursue EU membership paths.

While Montenegro has emerged as the clear frontrunner in the EU accession process – with accession treaty drafting underway and a target of membership by 2028 – Serbia’s own path remains largely stalled, with no new negotiating chapters opened in years and persistent concerns over democratic backsliding and foreign policy alignment, leaving Belgrade visibly uneasy as another former Yugoslav republic edges closer to leaving its orbit and fully joining the European mainstream.
