The Convention on the Prohibition of the Use, Stockpiling, Production and Transfer of Anti-Personnel Mines and on their Destruction, known informally as the Ottawa Treaty, the Anti-Personnel Mine Ban Convention, or often simply the Mine Ban Treaty, aims at eliminating anti-personnel landmines (AP-mines) around the world. To date, there are 164 state parties to the treaty. One state (the Marshall Islands) has signed but not ratified the treaty, while 32 UN states, including China, Russia, and the United States have not; making a total of 33 United Nations states not party.
