Foreign Ministers Urge Action on CTBT

More than 50 foreign ministers and senior government representatives met Sept. 27 at the United Nations to call for prompt action toward entry into force of the 1996 Comprehensive Test Ban Treaty (CTBT).

One hundred eighty-three states have signed the treaty, and 161 have ratified it. But under the terms of the treaty, eight more listed in Article XIV of the treaty, including the United States and China, must ratify it to achieve entry into force.

This year’s conference on facilitating entry into force, the eighth such meeting held since 1999, adopted a final declaration reaffirming the participants’ “determination to take concrete steps towards early entry into force” and pledging “support for bilateral, regional, and multilateral outreach initiatives” to that end. The conference did not produce a work plan for such an effort.

In an effort to spur progress, the new executive secretary of the Preparatory Commission for the Comprehensive Test Ban Treaty Organization (CTBTO), Lassina Zerbo, announced the formation of 18-member Group of Eminent Persons to boost national and international efforts to bring the treaty into force. It includes several former foreign and defense ministers and senior diplomats, plus the co-chairs of the Sept. 27 conference, Hungarian Foreign Minister János Martonyi and Indonesian Foreign Minister Marty Natalegawa.

U.S. and Chinese officials reiterated their support for the treaty, but did not make any commitments on ratification. Mirroring comments made at the 2011 conference, Rose Gottemoeller, the acting U.S. undersecretary of state for arms control and international security, said that “there are no set time frames to bring the treaty to a vote, and we are going to be patient, but persistent in our outreach efforts.” Pang Sen, director-general of the Chinese Foreign Ministry’s Arms Control Department, pledged that his government would continue to “push forward the deliberation process” for Chinese ratification.

In August, following a visit by Zerbo to Beijing to meet with Foreign Minister Wang Yi, China agreed to transmit data from the CTBTO’s monitoring stations in China to the organization’s International Data Center (IDC) in Vienna. According to an Aug. 7 CTBTO press statement, “This is part of the testing and evaluation process that marks the first formal step towards certification of the monitoring stations in China.”

The International Monitoring System will consist of 337 monitoring facilities when complete. Around 85 percent have already been installed and are sending data to the IDC. To date, 10 of the 11 CTBTO monitoring stations hosted by China have been built.
