This research aims to analyze a few ASEAN (Association of South East Asian Nations) member countries, that is Singapore, Malaysia, and Indonesia, in terms of multicultural policy and multicultural education from historic viewpoint in order to find out any implications for Korea. Unlike western region faced by the accommodative multculturalism, this research finds that, those ASEAN countries suffers from colonial legacy of the “divide and conquer” policy and labor import policy derived by the imperial powers. As a result, those countries have incorporated a variety of people and religion with differing economic status and are now trying to overcome those differences to create a unity among those people through education of language, religion, and/or ethics. This research findings imply that multicultural education at schools or at home need to start from children's identity education focusing on the small group affiliation they belong to but move forward to emphasize letting them enable to enjoy national unity in the long run. Regardless of their affliated group, moreover, they should be able to find out equal opportunity to devote themselves to development of the country they stay at while enjoying their personal lives. Last but not the least, globalisation trend has to be reflected in multicultural education program, particularly for Korea based on the open economy system, in such a way as to add more contents over Muslim and Chinese people which gains more popularity in global economy. And a national holiday or a day of celebration for multi-cultural life may be designated for convergence of various people and religion.
