The Samsung-owned dredging barge arrived in Gangjeong on June 20 to deliver blocks of concrete for a controversial South Korean naval base. Gangjeong sits on the south side of Jeju Island, the only place in the world to receive “triple crown status” from UNESCO for its unique geography. The former Roh Moo Hyun government also designated Jeju as a “peace island” as a form of apology for a government-sponsored massacre that took place there in 1948. In May 2009, when South Korean government confirmed the decision to place a naval base on Jeju, an opposition movement immediately formed.
