India has been seeking membership to the 48-member nuclear club, whose members can trade in and export nuclear technology. NSG is a powerful multinational body concerned with reducing nuclear proliferation.

India's inclusion into this group is an internal matter of the group. It needs prudence and caution and thorough discussions among all members."
