On 23 October 2006, Montenegro deposited its instrument of succession to the Mine Ban Treaty, thus becoming the 152nd State Party to the treaty.
After the split of Serbia-Montenegro, a State Party since 2003, Serbia automatically remained as a State Party and the ICBL wrote to the Montenegro Minister of Foreign Affairs urging him to clarify his country's status regarding the MBT.
Together, Serbia and Montenegro had begun to destroy stockpiled antipersonnel mines in August 2005 and by March 2006 had destroyed 649,217 mines, almost half of the total stockpile. In Montenegro, the Regional Center for Underwater Demining initiated a general survey of contamination in Plav and Rozaje municipalities in May 2006. No civilian casualties were reported during 2005.
