North Korea
Japan tried to suppress Korean traditions and culture and ran the economy primarily for its own benefit. Korean resistance groups known as Dongnipgun (Liberation Army) operated along the Sino-Korean border, fighting guerrilla warfare against Japanese forces. Some of them took part in allied action in China and parts of South East Asia. One of the guerrilla leaders was the communist Kim Il-sung, who later became the first leader of North Korea.
April 2018 inter-Korean summit
The April 2018 inter-Korean summit took place on April 27, 2018 on the South Korean side of the Joint Security Area, between Moon Jae-in, President of South Korea, and Kim Jong-un, Chairman of the Workers' Party of Korea, and Supreme Leader of North Korea. The summit was the third inter-Korean summit – and the first in eleven years. It was also the first time since the end of the Korean War in 1953 that a North Korean leader entered the South's territory; President Moon also briefly crossed into the North's territory.
