Efforts continue to get treaty banning nuclear test explosions to enter into forceListen / Banning all nuclear test explosions everywhere on the earth's surface, in the atmosphere, underwater and underground is the aim of the Comprehensive Test Ban Treaty.
Lassina Zerbo, the new Executive Secretary of the Preparatory Commission for the Comprehensive Nuclear-Test-Ban Treaty Organization (CTBTO), said over 90 per cent of countries said 'no' to nuclear test explosions.
So far, 183 countries have signed the treaty and of these, 159 have ratified.
However, he added that the treaty has to be ratified by eight countries namely China, Egypt, India, Iran, Israel, North Korea, Pakistan and the United States, for it to enter into force.
He discussed the challenges and progress made so far with UN Radio's Donn Bobb.
