Heh, check out South Korea.
“South Korea, not very tolerant, is an outlier. Although the country is rich, well-educated, peaceful and ethnically homogenous – all trends that appear to coincide with racial tolerance – more than one in three South Koreans said they do not want a neighbor of a different race. This may have to do with Korea’s particular view of its own racial-national identity as unique – studied by scholars such as B.R. Myers – and with the influx of Southeast Asian neighbors and the nation’s long-held tensions with Japan.”
