The Antarctic Treaty was signed on December 1, 1959 in Washington and became effective on June 23, 1961.
Through it, a normative framework was provided in relation to: the peaceful use of Antarctica; cooperation for scientific research; information exchange; the inspection regime for activities carried out in the Antarctic; the status quo of the territorial claims of seven of the signatory countries; and norms and conventions for the conservation of resources and the environment.
The Treaty designates Antarctica as a region of peace and cooperation, also addressing issues related to claims of sovereignty. It establishes that: "in the interest of all humanity, Antarctica will continue to be used exclusively for peaceful purposes and will not become the scene or object of international discord".
The Treaty was signed by Argentina, New Zealand, Australia, Norway, Belgium, South Africa, Russia, Chile, France, Great Britain, Japan and the United States.
