Large voluntary contribution by the United States
This latest donation is the largest single contribution of its kind to the organization to date and comes only weeks after the United States pledged a voluntary in-kind contribution valued at $8.9 million to the CTBTO. The earlier pledge will underwrite contribution in-kind projects implemented by U.S. agencies in coordination with the CTBTO that support the further development of the full range of CTBTO verification and monitoring activities to detect nuclear tests, including enhancing radionuclide and noble gas detection technologies, refining seismic detection techniques, and supporting auxiliary seismic stations.

I am extremely grateful to the United States for its generous contribution. These large voluntary contributions are a further demonstration of an outstanding commitment to the CTBTO.
