The concept of social exclusion is originated from Europe. Combating social exclusion has not only been promoted and applied by the European Union (EU) extensively, but has also become an important social policy for implementing practical measures. In Taiwan, new immigrants usually encounter many challenges to adapt to the new society. Some are even likely to become target of social exclusion. The purpose of the paper is to analyze the EU policies to combat social exclusion and compare them to policies of Taiwan's new immigrants. Both EU and Taiwan focus on social rights and employment protection. However, compared with EU's "Third Country Nationals", Taiwan's new immigrants receive better medical care, rights to education and some other social rights. In terms of policy implementation, EU employs open coordination law and encourages social partners to combat social exclusion and solve unemployment problems. In contrast, all policies of Taiwan's new immigrants, come from central government while local governments and civilian organizations play limited role in policy formulation and implementation.
