Indonesia became the 157th Country to adopt the CTBT (Comprehensive Test Ban Treaty)

Indonesia became the 157th country to adopt the Comprehensive Test Ban Treaty. Indonesia formalised ratification of the nuclear test ban treaty on 6 February 2012 at the United Nations.

The Association of Southeast Asian Nations (ASEAN) completed its talks on the regional weapons free zone in 2011 and the 10 member states are now completing ratification of that treaty. The Southeast Asia Nuclear Weapon-Free Zone treaty commits ASEAN's 10 member states not to develop, manufacture or otherwise acquire, possess or have control over atomic weapons.
