Alumni of the U.S. Peace Corps and young Korean volunteers pose with PeKO, the mascot of the Korea International Cooperation Agency (KOICA), at the agency's headquarters in Seongnam, Gyeonggi Province, Thursday. The American participants, who served as volunteers in Korea roughly 50 years ago, were visiting the country through the U.S. Peace Corps Volunteers Revisit Program organized by the Korean government.
