Definition

In plain language

A zone of peace is a region that countries try to keep free from war, foreign armies and nuclear weapons. It is more a political goal than a strict legal status.

Academic definition

A zone of peace is a political and quasi-legal concept advanced primarily by developing States from the 1970s onwards, designating a geographic area (often a sea or a region) that should be free from military conflict, foreign military presence and nuclear weapons. Unlike nuclear-weapon-free zones established by treaty, zones of peace were never defined by a binding instrument of international law and remained contested. They share affinities with demilitarisation, neutralisation and nuclear-weapon-free zones but lack the formal legal architecture of those regimes. Proposals for an Indian Ocean Zone of Peace and a South Atlantic Zone of Peace illustrate the concept’s political rather than strictly legal character.
