The Ottawa Treaty, also known as the Mine Ban Treaty, is an international agreement that aims to eliminate the use of anti-personnel landmines. Adopted in 1997 in Ottawa, Canada, the treaty prohibits the production, stockpiling, and transfer of these mines. It also requires signatory countries to clear mined areas and assist victims of landmines. As of October 2023, over 160 countries have ratified the Ottawa Treaty, demonstrating a global commitment to reducing the dangers posed by landmines. However, some nations, including the United States, Russia, and China, have not signed the treaty, which raises concerns about its overall effectiveness in achieving its goals.
