Today in Korean history

In 1999, North Korea challenged the validity of the Northern Limit Line (NLL) in the Yellow Sea dividing North and South Korea. The NLL, established by the United Nations Command at the end of the Korean War in 1953, was abandoned by North Korea.

In 2000, South Korea took steps towards reconciliation with North Korea by returning 63 former North Korean spies to Pyongyang. These individuals had served prison sentences of up to 40 years.

In 2010, a political scandal erupted when the ruling Grand National Party expelled Representative Kang Yong-seok. He was accused of making sexist comments about women's appearances during a dinner with college students in late July.

In 2018, President Moon Jae-in appointed his top security adviser, Chung Eui-yong, to a special envoy role to North Korea. This envoy led a delegation of five to Pyongyang, where they agreed to hold a summit between Moon and North Korean leader Kim Jong-un from September 18 to 20.
