Abstract: Brezhnev adjusted domestic and foreign policies, and strengthened economic and military assistance to DPRK (Democratic People’s Republic of Korea) after he took office, so Kim Il-sung relaxed his attitude towards Soviet Union. Later, the “Cultural Revolution” broke out in China and the ultra-left foreign policy criticized the Workers’ Party of Korea as revisionism. Meanwhile, the Red Guards and rebels made a series of conflicts on the border between China and North Korea. This infuriated Kim Il-sung and the Sino-DPRK relations reached rock bottom. However, Mao Ze-dong himself never criticized DPRK and Kim Il-sung did not want to deteriorate the relation with China. Under the sudden tension on Korean Peninsula during 1968-1969, the U.S. adopted tough policies towards DPRK. Hence, DPRK needed strong support from China. Meanwhile, with the armed conflict on Zhen-bao Island which turned the Sino-Soviet relations into the ice point, China intended to eliminate the tensions with neighboring countries and urged to repair its relations with DPRK. Choe Yong-gon received an invitation to visit China unexpectedly on September 30, 1969 and appeared at Tiananmen Rostrum afterwards. China and DPRK gradually resumed friendly relations. However, the disputes between China and DPRK were just postponed rather than solved.
