ASEAN BAC members are appointed by their respective Governments comprising high-level CEOs of companies from each member country and represented by 3 members per member country, with one representing the interest of small and medium-sized enterprises. Government focal points, at the Ministerial level, have been assigned to assist ASEAN BAC to fulfill its mandate.

In carrying out its objectives, ASEAN BAC holds regular meetings across ASEAN countries and engages in various ASEAN level forums to meet with government and private sector representatives so that all stakeholders concerned have the full understanding, acceptance, and ownership of the ASEAN integration process.
