Democratic Justice Party
Kang returned to South Korea in 1976, taking up the post of graduate school dean at the Hankuk University of Foreign Studies. His first foray into politics occurred in 1978 when he was appointed head of the Institute of Foreign Affairs and National Security, the training institute of the Ministry of Foreign Affairs. He then served as the Ambassador to the United Kingdom and Ireland (1981-84), and the Vatican (1984-87). After the pro-democracy protests of 1987, Kang ran for election and was elected to the 13th National Assembly as a member of the ruling Democratic Justice Party.
