The importance of ICT has been increasing time by time. Seeing the ICT development throughout the times has been affected the development of other sectors positively. Furthermore, ICT development enables the easier and faster cooperation and integration of other sectors within and among states. In regard to ASEAN, ICT plays the main role of better integration within and among its member states since its establishment in 1967. I can assure that without ICT development in ASEAN, the ASEAN Free Trade Area will be taken into force later than 1992; the establishment of ASEAN Community will take into force probably in the next 10 years. Moreover, most of cooperation and integration in ASEAN nowadays is ICT-based, so then the easier and faster agreement will be possible. Nonetheless, there remain obstacles for ASEAN integration along with the ICT development gap within and among ASEAN member states. In this article, I will specifically concern on the action that has been taken from certain elements/actors to narrowing the ICT development gap as well as its parameters. Eventually, I will recommend the possible solution that probably can be taken to close the gap as well as to foster the ASEAN integration.
