The Convention on the Prohibition of the Use, Stockpiling, Production and Transfer of Anti-Personnel Mines and on their Destruction of 1997, 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 (APLs) around the world.
By August 2025, 162 states had ratified or acceded to the treaty. Major powers, which are also past and current manufacturers of landmines, are not parties to the treaty. These include the United States, China, and Russia. Other non-signatories include India and Pakistan.
In 2025, Poland, Lithuania, Latvia, Estonia and Finland formally began the procedure to withdraw from the Ottawa Treaty. The three Baltic States, Finland and Poland completed the withdrawal in December 2025, January 2026 and February 2026 respectively. Amidst use of mines by non-signatory belligerent Russia during the Russo-Ukrainian War, Ukraine has not followed the treaty and in 2025 also announced the intent to withdraw, though the treaty stipulates that it should remain in effect until the end of the conflict.
