The Treaty has three Protocols. :Under
Protocol I, the
United States,
France, the
United Kingdom,
Russia and the
People's Republic of China are invited to agree not to use or threaten to use a nuclear explosive device against any Treaty party or against any territory of a Protocol III party within the African zone. :Under
Protocol II, the United States, France, the United Kingdom, the Russian Federation and China are invited to agree not to test or assist or encourage the testing of a nuclear explosive device anywhere within the African zone. :
Protocol III is open to states with dependent territories in the zone and obligates them to observe certain provisions of the Treaty with respect to these territories; only Spain and France may become Parties to it. The United Kingdom, France, the Russian Federation and China have signed and ratified the Protocols, but the United States has yet to ratify.
Spain has neither signed nor ratified Protocol III. The
United States has supported the concept of the denuclearization of Africa since the first
United Nations General Assembly resolution on this issue in 1965 and has played an active role in drafting the final text of the Treaty and Protocols. The United States signed Protocols I and II in 1996, but has not ratified them. In May 2010,
U.S. Secretary of State Hillary Clinton announced that the
Obama Administration would submit these protocols to the
U.S. Senate for advice and consent to ratification. The status of the
Indian Ocean island of
Diego Garcia, controlled by the United Kingdom and used as a military base by the United States, with regard to the Treaty is unclear. Diego Garcia is part of the
Chagos Archipelago claimed by Mauritius. The other islands of the Chagos Archipelago are considered in Africa and are under the treaty, but neither the United States nor the United Kingdom recognizes Diego Garcia as being subject to the Treaty. ==Enforcement==
