The Missile Technology Control Regime (MTCR) is an informal association of governments with common interests in missile, unmanned air vehicle, and related technology nonproliferation. It began with France, Germany, Italy, the United Kingdom, and the United States with an interim agreement to control nuclear-capable ballistic missiles. Its goal is to limit risks of proliferation by controlling transfers to delivery systems capable of weapons of mass destruction. States must follow laws and procedures which include information-sharing. There is no formal mechanism to ensure compliance.
