<P> Instead, the' Gandhi Plan', put forward in 1988, proposed the revision of the Non-Proliferation Treaty, which it regards as inherently discriminatory in favor of the nuclear - weapon States, and a timetable for complete nuclear weapons disarmament . It endorsed early proposals for a Comprehensive Test Ban Treaty and for an international convention to ban the production of highly enriched uranium and plutonium for weapons purposes, known as the' cut - off' convention . </P> <P> The United States for some years, especially under the Clinton administration, pursued a variety of initiatives to persuade India and Pakistan to abandon their nuclear weapons programs and to accept comprehensive international safeguards on all their nuclear activities . To this end, the Clinton administration proposed a conference of the five nuclear - weapon states, Japan, Germany, India and Pakistan . </P> <P> India refused this and similar previous proposals, and countered with demands that other potential weapons states, such as Iran and North Korea, should be invited, and that regional limitations would only be acceptable if they were accepted equally by China . The United States would not accept the participation of Iran and North Korea and these initiatives have lapsed . </P> <P> Another, more recent approach, centers on' capping' the production of fissile material for weapons purposes, which would hopefully be followed by' roll back' . To this end, India and the United States jointly sponsored a UN General Assembly resolution in 1993 calling for negotiations for a' cut - off' convention . Should India and Pakistan join such a convention, they would have to agree to halt the production of fissile materials for weapons and to accept international verification on their relevant nuclear facilities (enrichment and reprocessing plants). It appears that India is now prepared to join negotiations regarding such a Cut - off Treaty, under the UN Conference on Disarmament . </P>
