This study examines the crisis that children in South Korea face on a daily basis, investigates the current situation and the challenge of child welfare policies in South Korea, and contemplates the purpose and contents of UNICEF Child Friendly Cities (CFC). The goal of this study is to determine what is the possible contribution that CFC can make for the improvement of child welfare at the local level. Following are the results drawn from the case study of Seongbsuk-gu, which is one of the districts of Seoul. Seongbuk-gu is the first Child Friendly City in South Korea. First, Seongbuk-gu established its own set of universal policies for child welfare. Second, the organizational capability stands out in terms of its implementation of child policies. Third, it has an established mid-and-long-term perspective for the implementation of its child policies. Most importantly, it has developed a number of programs which vary in their implementations and objectives, depending on regional characteristics and needs. For the sake of the overall improvement of child welfare in South Korea, the establishment of CFC is highly recommended in order to raise the importance and the priority of policy-making directed towards the child sector at the local level and to strengthen the delivery system of policies related to children
