Each State Party “undertakes to destroy or ensure the destruction of all stockpiled anti-personnel mines it owns or possesses, or that are under its jurisdiction or control, as soon as possible but not later than four years after the entry into force of this Convention for that State Party.”
Notwithstanding the obligation to destroy all stockpiled anti-personnel mines, under Artuicle 3States Parties may retain “a number of anti-personnel mines for the development of and training in mine detection, mine clearance, or mine destruction techniques.” This number “shall not exceed the minimum number absolutely necessary” for these purposes.
Under the Oslo Action Plan, States Parties should "review the number of mines retained to ensure that they do not exceed the minimum number absolutely necessary for permitted purposes, and will destroy all anti-personnel mines that exceed that number. The States Parties will report annually by 30 April on the use of retained mines and on their destruction."
