Here is another article in the Times regarding Chinatowns in Korea. It talks about how the ROK government wants to develop a Chinatown in Incheon, but has not had much success thus far. One of the reasons cited for the lack of Chinese actually living in Chinatown is the fear of Chinese influence due to the history between the two nations.
On another note, it seems like there have been a lot of articles on Korean culture in mainstream U.S. media recently. As someone mentioned in class, I guess this could be one positive outcome of the North Korea situation.
