The Republic of Korea has long been known as a homogenous country, but due to struggles with a labor shortage and an aging society, the nation has been actively allowing foreigners to work and settle in the country since early 2000.

Many see such policies as a positive move for the country's future but others strongly oppose them. This episode of Asia Insight shows how South Korea is gearing up for change to become a multi-cultural society.
