Malaysia Ratifies the Comprehensive Test Ban Treaty

01.22.08 | 1 min read | Text by Steven Aftergood

Last week, Malaysia ratified the Comprehensive Test Ban Treaty (CTBT), bringing the total number of Treaty ratifications to 143, according to a CTBT Organization news release.

Among Southeast Asian nations, “Cambodia, the Lao People’s Democratic Republic, Malaysia, the Philippines, Singapore and Vietnam have now ratified the CTBT, whereas Brunei Darussalam, Indonesia, Myanmar and Thailand have yet to ratify it.”

To enter into force, the Treaty must be ratified by ten additional states with nuclear programs, including the United States, North Korea, Israel, China, Pakistan and Iran.

If and when that happens, the technical capability to verify compliance with the Treaty will be well in hand, according to a recent statement from the American Geophysical Union.

“When implemented, the American Geophysical Union and the Seismological Society of America are confident that the combined worldwide monitoring resources will meet the verification goals of the CTBT,” the AGU reaffirmed last month.

Inspections Without Inspectors: A Path Forward for Nuclear Arms Control Verification with “Cooperative Technical Means”

This report outlines a framework relying on “Cooperative Technical Means” for effective arms control verification based on remote sensing, avoiding on-site inspections but maintaining a level of transparency that allows for immediate detection of changes in nuclear posture or a significant build-up above agreed limits.
