This article examines the limitations of the gender mainstreaming discourse regarding the issue of childcare by women in South Korea, an area of responsibility that was transferred from the Ministry of Health and Welfare (MHW) to the Ministry of Gender Equality (MGE)1 in 2003. Through employing a discursive institutionalism approach, this article articulates that whilst the gender mainstreaming discourse has been interpreted at the surface level of politics, it has been formulated differently behind the scenes due to various policy interests. I argue that the discourse has remained at the level of superficial political rhetoric with underdeveloped understanding about the relationship between childcare and gender, thus retaining a stereotypical view of women as caregivers.
