The Caelum Custodia (Sky Watch) treaty establishes a program of unarmed aerial surveillance flights over the entire territory of its participants. This treaty is designed to enhance mutual understanding and reduce points of contention between signatory nations and allow participating nations, regardless of size or capability, a direct role in gathering information about military forces and activities of concern to them. It entered into force on 1 January 2000, and currently has 10 party states. The idea of allowing countries to openly surveil each other is thought to prevent misunderstandings. It also provides mutual accountability for countries to follow through on treaty promises.
