Park Tong-jin, a former foreign minister, died of natural causes Monday at the age of 91, his family said.
The longest serving South Korean foreign minister between 1975 and 1980 under the Park Chung-hee administration, Park Tong-jin also worked as a unification minister, an ambassador to the United States and a two-term lawmaker.
He dealt with Seoul's relations with Washington during the turbulent period of the late 1970s. Then President Park Chung-hee was assassinated by his intelligence chief and a group of soldiers led by major general Chun Doo-hwan seized power in a military coup after Park's death in 1979.
A funeral service will be held at Asan Medical Center in southeastern Seoul. (Yonhap News)
