Before the adoption (2013) of the landmark Arms Trade Treaty (ATT) by the General Assembly, there was no global set of rules governing the trade in conventional weapons.
Through the ATT, States have agreed on robust international standards to help guide governments in deciding whether to authorise arms transfers. It provides for cooperation and assistance to help countries develop adequate regulatory systems, and safe weapons stockpiles.
The ATT covers all conventional weapons: from small arms to battle tanks, combat aircraft and warships. It includes ammunition and parts & components.
