The Intergovernmental Coordination Group for the Pacific Tsunami Warning and Mitigation System (ICG/PTWS) was first established by the IOC in 1965 as a cooperation mechanism for countries in the Pacific whose coastal areas are threatened by tsunamis. Through the ICG, Member States have designed and developed the Pacific Tsunami Warning and Mitigation System and work together to improve and sustain it. At its 27th session on 28-31 March 2017, the ICG/PTWS decided to continue the Regional Working Group on Tsunami Warning and Mitigation System in the South China Sea Region under the chairmanship of Mr. Chan Sai-Tick (China). In this context, I am pleased to inform you that the Ninth Meeting of the ICG/PTWS Regional Working Group on Tsunami Warning and Mitigation System in the South China Sea Region (ICG/PTWS-WG/SCS-IX) will be hosted by the National Marine Environment Forecasting Center (NMEFC) in Guanzhou, China, tentatively on January 12-14,2020.
