The ASEAN Declaration[1] or Bangkok Declaration is the founding document of Association of Southeast Asian Nations (ASEAN). It was signed in Bangkok on 8 August 1967 by the five ASEAN founding members, Indonesia, Malaysia, Philippines, Singapore, and Thailand as a display of solidarity against communist expansion in Vietnam and communist insurgency within their own borders. It states the basic principles of ASEAN: co-operation, amity, and non-interference.[2] The date is now celebrated as ASEAN Day.[
