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 anti-personnel 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.”

A total of 71 States Parties have reported that they retain antipersonnel mines for training and research purposes, of which 40 have retained more than 1,000 mines and three (Finland, Turkey, and Bangladesh) have each retained more than 12,000 mines. Eighty-six States Parties have declared that they do not retain any antipersonnel mines, including 33 states that stockpiled antipersonnel mines in the past.
