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 to a range of at least 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. History The Missile Technology Control Regime (MTCR) was established in April 1987 by the G7 countries: Canada, France, Germany, Italy, Japan, the United Kingdom, and the United States. It was created to curb the spread of unmanned delivery systems for nuclear weapons, specifically systems which can carry a payload of for . The MTCR applies to exports to members and non-members. An aide-mémoire attached to the agreement says that it does not supersede prior agreements, which NATO members say allows the supply of Category 1 systems between NATO members. An example is the export by the United States of Trident missiles to the United Kingdom for nuclear-weapons delivery. At the annual meeting in Oslo from 29 June to 2 July 1992, chaired by Sten Lundbo, it was agreed to expand the MTCR's scope to include nonproliferation of unmanned aerial vehicles (UAVs) for weapons of mass destruction. Prohibited materials are divided into two categories, which are outlined in the MTCR Equipment, Software, and Technology Annex. Thirty-five nations are members, with India joining on 27 June 2016. According to the Arms Control Association, the MTCR has been successful in helping to slow (or stop) several ballistic missile programs: "Argentina, Egypt, and Iraq abandoned their joint Condor II ballistic missile program. Brazil and South Africa also shelved or eliminated missile or space launch vehicle programs. Some former Warsaw Pact countries, such as Poland and the Czech Republic, destroyed their ballistic missiles, in part, to better their chances of
