The Missile Technology Control Regime (MTCR) was established in April 1987 by the G7 countries: Canada, France, Germany, Italy, Japan, Great Britain, and the United States.
The MTCR was created in order to curb the spread of unmanned delivery systems for nuclear weapons, specifically delivery systems that could carry a minimum payload of 500 kg a minimum of 300 km.
India has officially applied for membership of MTCR. United States, France and some other nations have publicly announced their support for India’s membership in the MTCR. However, at the summit in Rotterdam in October 2015, India was denied access to the MTCR, with Italy rumoured to be the dissenting party, probably as a consequence of the Italian Marine Case.
