to various cultural and political disputes, mostly related to the history of Japanese rule in Korea. Examples include the Japanese history textbook controversies and problems with the Japanese immigration system for Zainichi Koreans. South Korea's relations with North Korea thawed during the beginning of the Fifth Republic, and proposed unification plans were announced, but only held favorable conditions for their respective countries and was mostly used for propaganda. North Korean relations soured in 1983 after the Rangoon bombing, an attempted assassination of President Chun during a state visit in Rangoon, Burma. Three North Korean agents detonated a bomb at the Martyrs' Mausoleum intending to kill Chun during a wreath laying ceremony to commemorate Aung San. The blast killed 21 people, including four senior South Korean politicians: foreign minister Lee Beom-seok, minister of power resource Suh Sang-chul, economic planning minister and deputy prime minister Suh Suk-Joon, and minister for commerce and industry Kim Dong-Whie. In September 1984, relations improved when North Korea sent large quantities of aid to South Korea during major flooding. The aid was accepted by Chun despite the North Korean attempt on his life less than a year earlier. In 1985, Chun proposed an inter-Korean summit that was eventually held in September in Seoul. The summit was considered a success in inter-Korean relations, but the bombing of Korean Air Flight 858 on 29 November 1987 by North Korean agents damaged relations again. The Fifth Republic continued South Korea's openly pro-Western stance and promoted stronger diplomatic ties with NATO countries in Europe, hoping to form greater economic ties to the European Community. The Fifth Republic also began to establish diplomatic relations with various African and Asian countries, including the United Arab Emirates, Lebanon, Pakistan, Brunei, and Bhutan.
