International retailer Carrefour ranking the second in the whole world claimed to withdraw from Korean market in 2006, while Britain's largest retailer Tesco is currently the only multinational retailer who runs successfully in Korea. This thesis compares the different localization strategies of these two retailers in Korean market from the aspects of the brand culture, the operation model, the marketing technique and the human resource and operation management. Finally, the thesis reaches some experience and enlightenment deserved to be learnt from by Chinese retail enterprises, which focus on meeting the needs of ordinary consumers, resolving culture conflicts and making it possible for companies to capture the international market in terms of joint venture or cooperative enterprise.
