Bosnia expels Serbian diplomat after he attended Mladic funeral

Bosnia and Herzegovina (BiH) formally declared on 8 September that two Serbian embassy officials – military attaché Milan Dulanović and security‑intelligence adviser Darko Maksimović – are persona non grata and must depart within 24 hours. The diplomats’ diplomatic privileges were revoked because they attended a funeral in Belgrade for Ratko Mladić, a convicted war criminal.

BiH lies in the heart of the Balkan Peninsula, bordering Serbia to the east, Montenegro to the south, Croatia to the north, and possessing a 20‑kilometre stretch of Adriatic coastline at its southern tip. The country is largely mountainous, especially in the central and eastern Dinaric Alps, while the smaller Herzegovina region enjoys a Mediterranean climate with inter‑woven mountains and coastlines. Sarajevo, the capital, is the nation’s largest city and its political and economic hub.

In the early 1990s BiH endured the bloody Bosnian War, during which Serbian armed forces clashed with Croat and Bosniak groups, causing massive civilian casualties. Ratko Mladić, former commander of the Bosnian Serb Army, directed atrocities including the Srebrenica massacre. He was arrested by the International Criminal Tribunal for the former Yugoslavia (ICTY) in 1995 and sentenced to life imprisonment in 2017. Nevertheless, the Serbian government has long celebrated Mladić as a “national hero.” The recent funeral in Belgrade drew diplomats and politicians from several countries, provoking strong resentment from the BiH government and domestic constituencies.

BiH’s foreign ministry stated that the two Serbian diplomats attended the funeral in an official capacity, equating to an endorsement of a war criminal already condemned by the international community and violating the basic standards of diplomatic conduct set out in the Vienna Convention on Diplomatic Relations. The BiH president and interior ministry also called on Serbia to withdraw the officials immediately and warned that, should Serbia fail to cooperate, more stringent restrictions could be imposed on the Serbian embassy. Serbia’s foreign ministry responded that participation in the funeral was motivated by “personal sentiment” and “national tradition,” not an official position, and said it would engage in dialogue with BiH on the matter.

The diplomatic row underscores the Balkans’ lingering historical wounds and carries implications for regional stability and the European Union’s enlargement agenda. BiH is actively pursuing EU membership, but strained relations with neighboring Serbia over unresolved war‑time issues could slow accession talks. The broader international community has urged both sides to resolve disputes within a peaceful, legal framework and to avoid emotionally charged political ceremonies that might reignite ethnic antagonism.

For Taiwan, BiH’s action serves as a reminder that diplomatic interactions with former belligerent or conflict‑affected states must strictly adhere to international law and established diplomatic norms, avoiding symbolic gestures that could spark political controversy. Taiwan likewise navigates a complex diplomatic landscape, particularly in dealings with nations that have contentious historical legacies. Balancing the defense of sovereignty with respect for international justice, as illustrated by BiH’s handling of the episode, offers a useful reference point for managing regional security considerations.
