border treaties

International demarcation pacts

Border treaties are formal agreements between nations establishing the location and nature of their shared boundaries.

They define where one country ends and another begins, often resolving territorial disputes or formalizing lines drawn after wars.

Border treaties may also govern movement across boundaries, shared resources like rivers, and demilitarized zones: The border treaty granted fishing rights to both nations.
