Nuclear Weapon Free Zones

Nuclear Weapon Free Zones (NWFZs) prohibit the testing, stationing, development, and use of nuclear weapons inside the designated territory. These zones can range from single states to geographical regions or international areas. Within these zones, countries may only use nuclear energy for peaceful purposes. Their establishment is recognized by Article VII of the nuclear Non-Proliferation Treaty and the UN General Assembly outlined the criteria for NWFZs in 1975:

A nuclear-weapon-free zone shall, as a general rule, be deemed to be any zone, recognized as such by the United Nations General Assembly, which any groups of states, in the free exercise of their sovereignty, have established by virtue of a treaty or convention whereby:a. The statute of a total absence of nuclear weapons to which the zone shall be subject, including the procedure for the delimitation of the zone is defined;b. An international system of verification and control is established to guarantee compliance with obligations derived from that statute.

With NWFZs, countries can establish preventative disarmament measures without the cooperation of the nuclear weapon states and can thus establish a common security system. Discussions are currently ongoing for creating NWFZs in the Middle East, South Asia, Northeast Asia, and Central Europe. These regions are unique in that they include or are next to de facto or declared nuclear weapon states, a move that signals a switch from passive to active disarmament. The existence and success of the NWFZs is widely considered to be a positive step towards the goal of a nuclear-free world.

Nuclear weapon free zones in the world

Single State

  1. Mongolia (2000): Mongolia prohibited the manufacturing, storage, transport, dumping, and testing of nuclear weapons within its territory. The government is trying to achieve international recognition for this declaration and secure negative assurances.
  2. Austria (1999): Austria forbids manufacturing, transport, storage, and testing of nuclear weapons.
  3. New Zealand: Goes beyond the South East Asian Nuclear Weapon Free Zone requirements by refusing to allow foreign nuclear powered ships or those carrying nuclear weapons from docking. It also does not allow any foreign aircraft carrying nuclear weapons to land on its land.
  4. Philippines: On top of joining the South East Asian Nuclear Weapon Free Zone, the Philippines changed its Constitution to declare it free of nuclear weapons.

The treaty states that states parties cannot conduct research on, develop, manufacture, control, stockpile, or posses any nuclear weapons. States parties may only conduct peaceful nuclear related experiments. Critics of the treaty claim that it is obsolete due to the fact that the only African country to develop nuclear weapons, South Africa, dismantled its program long before the treaty become open for signatures.
