The Missile Technology Control Regime (MTCR) is a multilateral export control regime. It is an informal political understanding among 35 member states that seek to limit the proliferation of missiles and missile technology. The regime was formed in 1987 by the G-7 industrialized countries. The MTCR seeks to limit the risks of proliferation of weapons of mass destruction (WMD) by controlling exports of goods and technologies that could make a contribution to delivery systems (other than manned aircraft) for such weapons. In this context, the MTCR places particular focus on rockets and unmanned aerial vehicles capable of delivering a payload of at least 500 kilograms (1,100 lb) to a range of at least 300 kilometres (190 mi) and on equipment, software, and technology for such systems.
The MTCR is not a treaty and does not impose any legally binding obligations on partners (members). Rather, it is an informal political understanding among states that seek to limit the proliferation of missiles and missile technology.[1]
