what is better for ASEAN in the future ?if all countries in ASEAN united ?

ASEAN was preceded by an organisation called the Association of Southeast Asia, commonly called ASA, an alliance consisting of the Philippines, Malaysia and Thailand that was formed in 1961. The bloc itself, however, was established on 8 August 1967, when foreign ministers of five countries– Indonesia, Malaysia, the Philippines, Singapore, and Thailand– met at the Thai Department of Foreign Affairs building in Bangkok and signed the ASEAN Declaration, more commonly known as the Bangkok Declaration. The five foreign ministers– Adam Malik of Indonesia, Narciso Ramos of the Philippines, Abdul Razak of Malaysia, S. Rajaratnam of Singapore, and Thanat Khoman of Thailand– are considered as the organisation's Founding Fathers.^[10]
