Yang Sung-chul

He began working at the Hankook Ilbo as a reporter in October 1963, but received a scholarship in 1965 to study at the University of Hawaii at Manoa's East–West Center for his master's degree.

[4] He went on to the University of Kentucky for his doctoral studies, where he defended a dissertation comparing the South Korean April Revolution of 1960 which led to the resignation of Syngman Rhee and the May 16 coup the following year which brought Park Chung-hee to power.

While in the United States, he was one of the founding members of the Association of the Korean Political Scientists in North America and served as its Secretary-General.

[8] In May 2000, just in advance of the first Inter-Korean summit, South Korean newspapers began to report that Yang had been chosen as Seoul's next ambassador to the United States.

Stratfor analysed Kim's choice to nominate Yang, along with the naming of four-decade career diplomat and trade expert Hong Soong-young as ambassador to Beijing, as part of an effort to push forward the Sunshine Policy: the posting to Washington of Yang, an expert on North Korean affairs, symbolised the autonomy of Seoul's policies towards Pyongyang, while Hong's role was to improve relations with Beijing and ensure its support for inter-Korean reconciliation.
