evidence: On April 6, 1989, the Agreement between the United States of America (U.S.) and the International Atomic Energy Agency (IAEA) for the Application of Safeguards in Connection with the Treaty for the Prohibition of Nuclear Weapons in Latin America (US – IAEA Caribbean Territories Safeguards Agreement) entered into force, along with its original small quantities protocol (SQP). This comprehensive safeguards agreement, nearly identical in structure to agreements between the IAEA and non-nuclear weapon States, is documented in IAEA Information Circular 366 (INFCIRC/366). The Treaty for the Prohibition of Nuclear Weapons in Latin America (also known as the Treaty of Tlatelolco) provides a basis for the U.S. – IAEA Agreement in this area. The U.S. agreed to accept IAEA safeguards in U.S. territories in the zone of application of the Tlatelolco Treaty: the Commonwealth of Puerto Rico, the Virgin Islands of the United States, Navassa Island, Serranilla Bank, Baja Nuevo Bank (Petrel Island), and the U.S. Naval Station at Guantanamo Bay. For the US-IAEA Caribbean Territories Safeguards Agreement, an SQP is applicable as there are no nuclear facilities, as defined by IAEA, in the U.S. Caribbean Territories. The only nuclear material is held by licensees outside of facilities.
