United Nations General Assembly Resolution 3261 F of December 9, 1974, states that "obligations relating to the establishment of nuclear-weapon-free zones may be assumed not only by groups of states, including entire continents or large geographical regions, but also by small groups of States and even individual countries."
なお1974年12月9日の国連総会決議 3261 F では、「非核兵器地帯の設立は、複数の国や地域のグループだけでなく、少数の国、更には個々の国々も行える」としている。
