UN chief urges all countries to join legally-binding treaty against nuclear tests

29 August 2017 &#150 United Nations Secretary-General António Guterres has urged all countries to sign and ratify a global treaty that bans nuclear explosions on the Earth’s surface, in the atmosphere, underwater and underground.

&#8220More than 2,000 nuclear tests have been conducted over the past seven decades &#8211 from the South Pacific to North America, from Central Asia to North Africa. They have harmed some of the world’s most vulnerable peoples and pristine ecosystems,&#8221 the Secretary-General said in his message for the International Day against Nuclear Tests.

To ensure that no country could conduct another test, he urged all countries to sign and ratify the Comprehensive Nuclear-Test-Ban Treaty (CTBT).

To date, 183 countries have signed the CTBT and 166 have ratified it. For the treaty to enter into force, ratification is required from eight more of the so-called Annex 2 States. Of these, China, Egypt, Iran, Israel, and the United States, have yet to ratify it.

DPRK, India and Pakistan are among the 13 countries that have not signed the CTBT.

&#8220I urge all countries yet to join the CTBT to do so as soon as possible,&#8221 Mr. Guterres said. &#8220For almost 20 years, a global norm has existed against nuclear testing based on voluntarily unilateral moratoriums. I applaud this restraint, but it is not enough.&#8221

He noted that continued nuclear tests by DPRK demonstrate that &#8220even the strongest norm is no substitute for a legally-binding prohibition.&#8221

Overnight, DPRK fired a ballistic missile in violation of Security Council resolutions, Mr. Guterres said in a separate statement condemning the event and urging DPRK to fully comply with its international obligations.

The comments come on the International Day against Nuclear Tests, which is observed annually on 29 August, following the declaration of that day in a resolution unanimously adopted by the UN General Assembly in 2009.

The resolution called for increasing awareness and education &#8220about the effects of nuclear weapon test explosions or any other nuclear explosions and the need for their cessation as one of the means of achieving the goal of a nuclear-weapon-free world.&#8221 The resolution’s adoption also commemorated the closure of the Semipalatinsk nuclear test site in Kazakhstan in 1991.
