Foreign relations of South Korea
On January 18, 1952 The first president of South Korea Syngman Rhee declared that the vicinity of Dokdo was a territory of South Korea (Syngman Rhee line). Subsequently, some 3,000 Japanese fishermen who conducted fishery operations in this vicinity were captured. This incident, called the Dai Ichi Daihoumaru Ship case strained relations between South Korea and Japan.
South Korea–United States relations
The current South Korean President Moon Jae-in, elected in May 2017, has said he supports the continuation of sanctions against North Korea if it is aimed at bringing North Korea out of its “hermit” to the negotiating table. He also argued, at the same time, that he was against a “sanctions-only” approach toward North Korea. His approach to North Korea is similar to Kim Dae-jung's Sunshine Policy, which only continued up to the Roh Mu-hyun's administration.
