Aimed at strengthening regional economic integration，ASEAN initiated the ASEAN Economic Community （AEC） in 2003. The ASEAN Economic Community Blueprint rectified at the 13th summit outlined the framework of AEC，while ASEAN Charter，launched at the same summit，will provide the basic institutional support for the smoothly progress of AEC. But in this paper，we will show that although the endeavors on economic integrations during last four decades may serve as fundamental bricks of AEC which will make it easier to realize，AEC will confront many challenges because it’s an ambitious program that need close cooperation and coordination of all members to keep going forward. And this may go beyond what ASEAN Charter can provide. Nevertheless，ASEAN can still fulfill the task and declare in 2015 or even before that the success of an AEC，albeit with strong ASEAN character.
