Written by Nguyễn Thị Thanh Hà and Isabelle Cheng. It has been more than three decades since Southeast Asian nationals began to work and establish their families in Taiwan. Men and women from the Philippines, Thailand, Indonesia, Vietnam and Cambodia fill the labour shortage in construction, fishing, manufacturing, care and agricultural industries, whilst the women became members of Taiwanese society because of their marriage and family formations. This ongoing regional migration flow has enriched the socio-cultural landscape of Taiwan, where multiculturalism becomes the prevailing normative value that respects and appreciates differences. Nevertheless, this development has not been smooth or unchallenged.
