How many mines have been retained for training purposes?
Article 3 of the Mine Ban Treaty allows a State Party to retain or transfer “a number of antipersonnel mines for the development of and training in mine detection, mine clearance, or mine destruction techniques…The amount of such mines shall not exceed the minimum number absolutely necessary for the above-mentioned purposes.”
The Monitor estimates that as many as 30 of the 33 states not party to the Mine Ban Treaty stockpile antipersonnel landmines. In 1999, the Monitor estimated that, collectively, states not party stockpiled about 160 million antipersonnel mines, but today the global collective total may be less than 50 million. It is unclear if all 30 states are currently stockpiling antipersonnel mines. Officials from the UAE have provided contradictory information regarding its possession of stocks, while Bahrain and Morocco have stated that they have only small stockpiles used solely for training purposes in clearance and detection techniques.
