Statement by the Minister for Foreign Affairs of Japan on the Approval by the Indonesian Parliament for Indonesia's Ratification of the Comprehensive Nuclear-Test-Ban Treaty (CTBT)

December 6, 2011

  1. I wholeheartedly welcome that the parliament of the Republic of Indonesia, which is one of 44 Annex 2 States whose ratification is needed for entering into force of the Comprehensive Nuclear-Test-Ban Treaty (CTBT), approved Indonesia's ratification of the Treaty on Tuesday, December 6. I believe that this is an important step forward for the Treaty's entry into force as it will encourage the remaining 8 Annex 2 States which have not ratified the treaty to ratify it.

  2. Toward the Treaty's early entry into force, Japan has been actively calling on and providing support to the said Annex 2 States as well as other countries that have not ratified the Treaty to ratify it. At the 7th Conference on Facilitating the Entry into Force of the Treaty held this September in New York, I called on countries which have not yet signed or ratified the Treaty to do so at the earliest possible time. For Indonesia, in addition to encouragements at high-level bilateral talks, Japan has invited government and parliamentary officials and experts to Japan, and has continuously appealed the importance of the Treaty. Mayors of Hiroshima and Nagasaki Cities and Mayors for Peace also sent letters addressed to the Chairman of the First Commission, the House of Representatives of the Republic of Indonesia this November.

  3. Japan will renew its call on the remaining 8 Annex 2 States and other non-ratifying countries to follow Indonesia's example and promptly ratify the Treaty. Japan will also continue making further diplomatic efforts for the Treaty's early entry into force, which is an important step for realizing "a world without nuclear weapons."

[Reference] The Comprehensive Nuclear-Test-Ban Treaty (CTBT)

  1. The CTBT bans nuclear weapon test explosions or any other nuclear explosion at any place, including outer space, the atmosphere, underwater and underground.

  2. Despite opening for signature in 1996, thus far the Treaty has not entered into force. For the Treaty to enter into force, all 44 countries listed in the Annex 2 to the Treaty (Annex 2 States)   need to ratify it. Japan ratified the Treaty in July 1997. Of the 44 Annex 2 States, China, Egypt, Iran, Israel and the U.S. have not ratified it, and India, North Korea and Pakistan have not signed it. Currently 182 countries have signed the Treaty and 155 countries have ratified it. (As of December 6, 2011. Ratifying countries are those that have deposited their instruments of ratification with the United Nations.)

  3. For encouraging Indonesia to ratify the Treaty, in 2007 and 2009 Japan invited members of the Indonesian government and parliament to Japan for exchange of opinions and visit to Japan's CTBT verification facilities to detect nuclear tests. Additionally, Japan has invited a total of 12 Indonesian experts to participate in the JICA's Global Seismological Observation training course, which Japan has been organizing every year since 1995 with the goal of offering the latest technologies and expertise in the field of global seismological observation, and training personnel capable of performing important roles in the nuclear test detection network.
