A buffer zone is generally a zonal area that lies between two or more areas (often, but not necessarily, countries), but depending on the type of buffer zone, it may serve to separate regions or conjoin them. Common types of buffer zones are demilitarized zones, border zones and certain restrictive easement zones and green belts. Such zones may be, but not necessarily, comprised by a sovereign state, forming a buffer state.
