CTBT brought closer to entry into force by Indonesia's ratification
On 6 February 2012, Indonesian Foreign Minister Marty Natalegawa met with United Nations Secretary-General Ban Ki-moon at the United Nations headquarters in New York, United States. In a special ceremony (video), Natalegawa submitted the instrument of his country's ratification of the Comprehensive Nuclear-Test-Ban Treaty (CTBT) to the Secretary-General personally - a rare exception for any ratification.
This formalizes Indonesia’s ratification, which has now officially become the 157th State to ratify the Treaty. It also brings down to eight the number of countries required to ratify the Treaty to become global law. The head of the Preparatory Commission for the Comprehensive Nuclear-Test-Ban Treaty Organization (CTBTO), Executive Secretary Tibor Tóth, also participated in the ceremony. A press briefing (video) followed the ceremony.

On 6 December 2011, the Indonesian parliament voted unanimously to ratify the CTBT. Tibor Tóth congratulated Indonesia’s parliamentarians for bringing the CTBT "a significant step closer to becoming global law. I welcome today’s outcome of the vote in the Indonesian Parliament to ratify the Treaty. By this historic decision, the
gap keeping the Treaty from entering into force has been narrowed down to eight countries," he said. The Indonesian ratification was welcomed by leaders around the world.

The vote took place around 12.00 local time - click to see video.

I am determined to ensure that Indonesia's decision today will create momentum to encourage others who are still holding out to do the right thing. And the only right thing is to ratify the CTBT now, no more procrastination, no more delaying because it is right, it is proper and it makes a more secure world.
“Indonesia will use its good relations to promote the Treaty in Asia and the Middle East and beyond and at the highest political level,” Hemly Fauzy, the Indonesian Parliament’s coordinator for the CTBT ratification process said during a recent visit by an Indonesian parliamentary delegation to the CTBTO headquarters in Vienna.
“We want our country to be at the vanguard of nuclear disarmament and non-proliferation,” said Fauzy. “We intend to extend our involvement in the CTBT beyond the Treaty’s ratification.” Support for the Treaty in the Indonesian Parliament was unanimous across its nine parties, he said.

This is the day when Indonesia reconfirmed its leadership, its leadership as a founder of the ASEAN and NAM. This leadership is about saying NO to nuclear weapons and it is about saying YES to the Treaty that is part of eliminating nuclear weapons.
Indonesia currently chairs the Association of Southeast Asian Nations (ASEAN), whose 10 Member States have also concluded the Bangkok Treaty establishing the most comprehensive nuclear-weapon-free zone on Earth. The CTBT has been signed by all ASEAN Member States. Three - Brunei, Myanmar, and Thailand - have still to ratify as do Indonesia’s neighbours Papua New Guinea, Sri Lanka and Timor Leste.

We will be making that appeal, that pressure and that encouragement to other countries...we have to create an irreversible sense of momentum.
