Last week my old Dartmouth classmate Michael Kim, now a professor of Korean history at Yonsei University, invited me to join him on a tour of the new Yonsei campus in Songdo. Songdo is an emerging "green city" built from scratch on a muddy stretch of reclaimed land near the Incheon airport. The foundations of the city seem to be constructed by driving concrete piles deep down into the mud and building upon them. Sound familiar? This is how Shanghai's Bund was built since the 19th century.
