The Asia and Pacific Office was established in 1948 at Melbourne, Australia. It was then named Far East and Pacific Office. Initially the Office was accredited to 12 States in the Far East and Pacific – Australia, Sri Lanka, Myanmar, China, India, Indonesia, Japan, Vietnam, New Zealand, Philippines, Thailand and Korea. The Regional Office was shifted to Bangkok and Thailand due to its geographical location and started operating from there with effect from 3 January 1955. The Office has grown significantly to the number of States to which it was accredited and currently the Asia and Pacific Office is accredited to 36 States as listed in the area of responsibility.
Since re-locating to Bangkok, ICAO has conducted three major Regional Air Navigation Sessions for Asia and Pacific Regions: 1973 in Honolulu, 1983 in Singapore, and 1993 in Bangkok. The Asia Pacific Air Navigation Planning and Implementation Regional Group were established by the ICAO Council It had its first meeting in April 1992, 1991 at the Regional Office. Since then, APANPIRG has been working towards ensuring continuous and consistent development of the Asia/Pacific Regional Air Navigation Plan and facilitating the implementation of the corresponding air navigation systems and services with due observance of the primacy of air safety, regularity and efficiency.
