Racism in South Korea has been recognized—particularly by the South Korean media—as a widespread social problem.
An increase in immigration to South Korea since the 2000s catalyzed more overt expressions of racism, as well as criticism of those expressions. Newspapers have frequently reported on and criticized discrimination against immigrants, in forms such as being paid lower than the minimum wage, having their wages withheld, unsafe work conditions, physical abuse, or general denigration.
In a 2010–2014 World Values Survey, 44.2% of South Koreans reported they would not want a foreigner as a neighbor. Racist attitudes are more commonly expressed towards immigrants from other Asian countries and Africa, and less so towards European and white American immigrants who can occasionally receive what has been described as "overly kind treatment". Related discrimination have also been reported with regards to mixed-race children, Chinese Korean, and North Korean immigrants.
Recent legislation—in particular, the Foreign Workers' Employment Act (2004) and Support for Multicultural Families (2008)—have improved the situation of immigrants, more efficiently protecting their human and labor rights. In 2011, the Korean military abandoned a regulation barring mixed-race men from enlisting, and changed the oath of enlistment to not reference racial purity (minjok) to citizenship. Similarly, related concepts have been withdrawn from school curricula. This has been accredited in part to international pressure—in particular, concern from the UN Committee on the Elimination of Racial Discrimination, which stated persistent ethnic-centric thinking in South Korea "might be an obstacle to the realization of equal treatment and respect for foreigners and people belonging to different races and cultures".
As of 2016, South Korea was still lacking an anti-discrimination law, which was recommended by the UN Human Rights Committee in 2015. The law has been reported stalled due to "lack of public consensus".
