Media Advisory - Indonesian Parliament to
ratify Comprehensive Nuclear-Test-Ban
Treaty on 6 December

Vienna, 5 December 2011

The Indonesia parliament will vote on the ratification of the Comprehensive Nuclear-Test-Ban Treaty (CTBT) on 6 December in its morning session. The Defense and Foreign Policy Commission approved the draft legislation by consensus on 30 November. The ratification is a major step towards bringing the CTBT, which bans all nuclear explosions, into legal effect. The Treaty effectively hampers both the first-time development of nuclear weapons as well as the enhancement of existing arsenals.

The decision demonstrates Indonesia's strong commitment to nuclear disarmament and non-proliferation and is expected to send a signal to the remaining eight States that have yet to ratify for the CTBT to become international law: China, Egypt, India, Iran, Israel, North Korea, Pakistan and the United States. Indonesia's ratification is also expected to encourage those Association of Southeast Asian Nations (ASEAN) States that have not yet ratified to do so, namely Brunei, Myanmar and Thailand.

Items of media interest

  • Media door stop interview with Indonesian Foreign Minister Marty Natalegawa, the Chairman of the First Commission, Mahfudz Siddiq, and CTBTO Executive Secretary Tibor Tóth at the Indonesian parliament directly after the ratification decision (session starts at 09:00 local time, CTBT is second item on the agenda).

  • Press Conference with Minister Marty Natalegawa and Executive Secretary Tibor Tóth at the Indonesian Ministry of Foreign Affairs at 15:25 local time.

Background on the CTBT

The CTBT bans all nuclear explosions by everyone, everywhere: on the Earth’s surface, in the atmosphere, underwater and underground. 182 countries have signed the Treaty, of which 155 (with Indonesia 156) have also ratified it. An unprecedented global verification regime with over 300 sensors monitors the globe around the clock for nuclear explosions to detect any violations to the Treaty.
