MANILA, Philippines — The Philippines has called on nations to uphold the moratorium on nuclear weapons testing in the face of escalating geopolitical tensions and increasing nuclear rhetoric.

Ambassador to Austria Evangelina Arroyo-Bernas stressed the importance of maintaining the global moratorium on nuclear weapons testing during the 65th Session of the Preparatory Commission of the Comprehensive Nuclear-Test-Ban-Treaty Organization (CTBTO) in Vienna.

In the event, the Philippines also highlighted the need to support efforts to sustain International Monitoring Stations (IMS) network as well as capacity building activities to ensure that station operators are equipped to operate the IMS equipment.

The IMS, consisting of 321 monitoring stations and 16 laboratories hosted by 89 countries, can detect any nuclear test explosions around the world, and has successfully detected all six declared nuclear tests conducted this century.

The Philippines has also reaffirmed its strong commitment to the CTBTO, which it highlighted as a cornerstone of the global nuclear disarmament and non-proliferation architecture. The CTBTO was convened in 1996.
