The treaty that was rejected by India as discriminatory because it prevented only non-nuclear countries from acquiring nuclear weapons is the Non-Proliferation Treaty (NPT). The NPT is an international agreement aimed at preventing the spread of nuclear weapons and technology, promoting disarmament, and facilitating the peaceful use of nuclear energy. However, India considered the treaty to be biased against non-nuclear states, as it distinguished between nuclear and non-nuclear countries, effectively denying the latter the ability to develop nuclear weapons while allowing the five nuclear-armed states at the time of the treaty's signing (the United States, the Soviet Union, the United Kingdom, France, and China) to retain their arsenals indefinitely.
