The culture globalization in the true meaning of the word is one which pursues the coexistence of many different cultures from around the world. However, to date, homogenization of culture is more prevalent than cultural diversity. Criticism of the homogenization of culture and reaction to the rootless culture which threatens cultural identities occurred from every country. Thus, scholar and government official discussed actively the ‘cultural diversity’. The result was “UNESCO Universal Declaration on Cultural Diversity”(2001) as well as “UNESCO Convention on the Protection and Promotion of the Diversity of Cultural Expressions”(2005). This paper aims to examine the process of development from “Declaration” to “Convention”, make a detailed study on the “Convention” and its significance. In succession, we work on how to integrate the “Convention” into the conception of “glocality”. We attempt to play up the matter that this “Convention” promotes the diversity of culture, aspires toward an authentic culture globalization which considers the global as well as the local, by advocating cultural rights of social minorities.
