Singapore ratifies Comprehensive
Singapore deposited its instrument of ratification of the Comprehensive Nuclear-Test-Ban Treaty (CTBT) with the Secretary-General of the United Nations on 10 November 2001, on the eve of the opening of the Conference on Facilitating the Entry into Force of the CTBT. Singapore is the 85th State Signatory and the fourth State of the Association of South-East Asian Nations to have ratified the Treaty. For the CTBT to enter into force, a further 13 of the 44 nuclear-capable States listed in Annex 2 to the Treaty need to ratify it.
Under the terms of the Treaty, a global network of 337 monitoring facilities is being established to verify Treaty compliance. International Monitoring System (IMS) facilities record data using four complementary technologies - seismic, hydroacoustic, infrasound and radionuclide - and are capable of registering vibrations from a possible nuclear explosion underground, in the seas and in the air, as well as detecting radioactive debris released into the atmosphere. The monitoring facilities transmit the data via satellite to the International Data Centre (IDC) in Vienna, where the data are used to detect, locate and characterize events. These data and IDC products are made available to the States Signatories for final analysis.
The CTBT bans any nuclear weapon test explosion or any other nuclear explosion anywhere in the world. Drafted at the Conference on Disarmament in Geneva, and adopted by the United Nations General Assembly on 10 September 1996, the Treaty was opened for signature on 24 September 1996 at United Nations Headquarters in New York.
