Between 1973 and 1979, Josip Broz Tito and Kim Il Sung exchanged no fewer than 25 items of correspondence. These sources shine light on North Korea’s engagement with the Third World, and later with the US, and underline the Yugoslav leader’s importance within Pyongyang’s foreign policy during the 1970s. This collection is introduced and analyzed by Martin Coles in a series of postings on Sources & Methods: "Neighbors in Non-Alignment: The Tito-Kim Correspondence, 1973-1979".
