Abstract:

50 years after first use of nuclear bombs, and testing of nuclear explosions in open atmosphere, the Comprehensive Nuclear-Test-Ban Treaty (CTBT) was opened for signature on 24 September 1996, and an absolutely unique international norm on nuclear testing was established. The Treaty bans nuclear explosions by everyone, everywhere: on the Earth's surface, in the atmosphere, underwater and underground. Now, the CTBT makes it very difficult for countries to develop nuclear bombs for the first time, or for countries that already have them, to make more powerful bombs. It also prevents the huge damage caused by radioactivity from nuclear explosions to humans, animals and plants. However, CTBTO's monitoring stations picked up an unusual seismic event in the Democratic People’s Republic of Korea (DPRK) on 3 September 2017. In this presentation we are considering some aspects of the present international policy, possible reasons of newly challenges in the international area, the importance to reinforce a joint call for the prompt entry into force of the CTBT, and increasing role of the Treaty in a global policy context.
