It is still not clear, however, what form the AEC will take. One form could be an “FTA-plus’’ arrangement, which includes some elements of a common market, e.g., free flow of capital, free flow of skilled labor, zero tariffson intraregional trade, but does not include a common external tariff. The other is other form is that of a “common market minus’’ arrangement that aims to create a fully integrated market but has areas where members of ASEAN will reserve deeper integration for a later stage.
