Technical assistance is an essential element in capacity building. The exchange of knowledge and technology is usually at the heart of disaster management assistance. Bilateral agreement is usually the most effective and efficient mechanism in requesting and delivering assistance. Previous agreement sets proper, clearer, and more familiar procedures for agencies on both sides to coordinate disaster operations. Evidently, in Thailand, after the Indian Ocean Tsunami in 2004, several United States agencies such as United State Trade and Development Agency (USTDA) and United State Agency for International Development (USAID) assisted the Thai government through the establishment of the National Disaster Warning Center, the deployment of the Tsunami Deep Ocean Buoy detection system, and the training on Incident Command System. This type of favorable bilateral relationship was also repeated in on-ground operations following Typhoon Haiyan in the Philippines, which relied upon joint forces and emergency teams from the United States.
