The Arms Trade Treaty (ATT) is an international agreement that regulates the trade of conventional arms, including weapons and ammunition. Adopted by the United Nations in 2013, the treaty aims to prevent the illicit trade and diversion of arms, ensuring that they are not used to fuel conflict, human rights abuses, or terrorism. Countries that ratify the ATT commit to implementing measures to control arms exports and imports. They must assess the potential risks of arms transfers and ensure that their trade practices align with international humanitarian law and human rights standards.
