In recent years, female marriage migration from China and Southeast Asia has significantly increased the number of foreign-born citizens in Taiwan. This article is a preliminary investigation into how political parties responded to the growing multicultural makeup of the national community between 2000 and 2012. We examine the content of the Understanding Taiwan textbook, the election publicity of the two major political parties, citizenship legislation, and the results of interviewing immigrant women. The findings show that the change in the ruling party did make differences in terms of both parties’ projection of immigrant women in election propaganda and citizenship legislation. However, inward-looking multiculturalism is practised by the two main political parties in Taiwan to forge national identity and enhance national cohesion rather than to promote the recognition of immigrants’ different cultural heritage.
