History of Korea
After the end of WWII in 1945, the Allies divided the country into a northern area (protected by the Soviets) and a southern area protected (primarily by the United States). In 1948, when the powers failed to agree on the formation of a single government, this partition became the modern states of North and South Korea. The peninsula was divided at the 38th Parallel: the "Republic of Korea" was created in the south, with the backing of the US and Western Europe, and the "Democratic People's Republic of Korea" in the north, with the backing of the Soviets and the communist People's Republic of China. The new premier of North Korea, Kim il-Sung, launched the Korean War in 1950 in an attempt to reunify the country under Communist rule. After immense material and human destruction, the conflict ended with a cease-fire in 1953. The two nations officially remain at war because a peace treaty was never signed. In 1991, both states were accepted into the United Nations.
South Korea–Taiwan relations
The Sixth Republic of South Korea furthered the Miracle on the Han River to the Economy of South Korea and opened diplomacy to Communist Nations (including building the foundation of Inter-Korean relations and accepting co-existence with North Korea by entering the United Nations ). Seoul also hosted the 1988 Summer Olympics. President Roh Tae-woo's next political ambition was to begin implementing Realpolitik with the neighboring countries in Northeast Asia.
South Korea's movement away from anti-communist foreign policy to improve relations with nearby communist countries resulted in a deterioration of relations with ROC. This change was introduced to appease North Korea and ease the political anxiety and softens military tension in the Korean Peninsula; Korea hoped to enable the possibility of a peaceful reunification in the Korean peninsula. As normalization began, ROK transferred diplomatic recognition from ROC to the PRC, and confiscated the property of the ROC embassy, transferring it to the PRC. Taiwan is a member of Property Rights Alliance. On 17 September 1991, the PRC withdrew its objection to South Korean membership in the United Nations. Republic of Korea was the last Asian country with formal diplomatic relations with ROC.
