Rangoon bombing

On 9 October 1983, South Korean President Chun Doo-hwan traveled to Rangoon (now Yangon), Burma, on an official state visit. He had planned to lay a wreath at the Martyrs' Mausoleum to honor Aung San, a founding figure of independent Burma who was assassinated in 1947. As members of the presidential delegation gathered at the mausoleum ahead of Chun's arrival, one of three bombs concealed in the roof detonated. The explosion tore through the assembled crowd, killing 21 people and injuring 46 others. Among the dead were four senior South Korean officials: Foreign Minister Lee Bum Suk, Minister of Power Resources Suh Sang-chul, Deputy Prime Minister and Economic Planning Minister Suh Suk-joon, and Minister of Commerce and Industry Kim Dong-hwi. Fourteen additional South Korean presidential advisers, journalists, and security officials were killed, along with four Burmese nationals, including three journalists. President Chun himself was not present at the mausoleum at the time of the blast; his car had been delayed in traffic, and the bomb is reported to have detonated prematurely after a ceremonial bugle signaling his arrival sounded ahead of schedule.

Burmese police investigation identified three suspects, described as a major and two captains of the Korean People's Army. Investigators determined the men had disembarked from a ship docked in Rangoon's port and received explosives through a North Korean diplomatic mission in the city. On the day of the bombing, two of the suspects, Kang Min-chul and Kim Jin-su, attempted suicide by detonating a hand grenade; both survived but sustained serious injuries, with Kang losing his right arm and Kim losing an eye and an arm. Both men were subsequently captured, with Kim Jin-su apprehended by a Burmese civilian, Darr Sann Ye, along with several other men, including Bo Gyi and Shwe Min Thar. A third suspect, Shin Ki-chul, evaded capture, killed three soldiers, and was ultimately shot dead. Kang Min-chul confessed to the operation and his links to North Korea, which allowed him to avoid a death sentence in favor of life imprisonment. Kim Jin-su refused to cooperate with investigators and was executed by hanging. North Korea denied any connection to Kang.

In the aftermath, Burma severed diplomatic relations with North Korea, and China — which had recently relayed a North Korean diplomatic request for trilateral talks — publicly reprimanded North Korea and avoided official contact with its representatives for months. The United States provided quiet military and logistical support to help repatriate survivors and the bodies of the deceased. In 1994, South Korea's representative to the United Nations linked the bombing to the later downing of Korean Air Flight 858, contributing to North Korea's continued designation as a state sponsor of terrorism.

Kang Min-chul remained imprisoned in Burma's Insein Prison for the rest of his life, becoming the country's longest-serving prisoner. He learned Burmese, converted to Christianity, and died of liver cancer on 18 May 2008 while being transferred to a hospital.
