noninternational

Noninternational is an adjective used to describe something that does not concern or involve more than one country. In legal and political contexts, the term is often encountered in contrast to international, particularly in the phrase noninternational armed conflict.

Noninternational armed conflict (NIAC) is a category in international humanitarian law that covers internal conflicts within a state, typically between government forces and organized non-state armed groups, or between such groups within the state's territory, where foreign involvement is not the main aspect. NIACs are governed by additional rules and conventions that reflect their internal nature, rather than by all of the provisions applicable to international armed conflicts.

NIACs are governed by Additional Protocol II to the Geneva Conventions of 1977, and by customary international humanitarian law. They are distinguished from international armed conflicts, which involve hostilities between states or cross-border interventions. Classification as NIAC affects the applicable protections for victims, the status of combatants, and the methods permissible in warfare, with some provisions of the Geneva Conventions applying differently or only partially.

Beyond law, noninternational is used generally to describe internal or domestic matters that do not cross borders, such as noninternational trade within a country or noninternational policy questions.
