Article XIV of the Comprehensive Nuclear-Test-Ban Treaty (CTBT) states that if the Treaty has not entered into force three years after the date of the anniversary of its opening for signature, a conference may be held upon the request of a majority of ratifying States. Such a conference is held to examine to what extent the requirements for entry into force have been met, and to decide on measures to accelerate the ratification process. Previous Conferences on Facilitating the Entry into Force of the Treaty were held in 1999, 2003 and 2007 in Vienna, and 2001, 2005, 2009, 2011, 2013 and 2015 in New York.
Pursuant to Article XIV, and at the request by a majority of States which have already deposited their instruments of ratification of the Treaty, the Secretary-General of the United Nations, in his capacity as the Depositary of the Treaty, will convene the tenth Conference on Facilitating the Entry into Force of the CTBT on 20 September 2017 in New York.
The Depositary’s status of signatures and ratifications of the Treaty can be found in the UN Treaty Collection.
