Kim and Oh (2001) reported the existence of implicit (nonconscious) prejudicial attitudes toward South and North Korea by South Koreans and by North Koreans who voluntarily defected to South Korea, although the two groups showed no difference in explicit (conscious) forms of prejudice. This study followed up on the explicit and implicit attitudes of South Koreans initially reported in 1998, by assessing the attitudes shortly after the North and South Korea Summit held in June 2000, as well as 2 years later (2002). A substantial reduction in South Koreans' explicit negative attitudes against North Korea was found shortly after the summit, but the reduction waned 2 years later, relative to the initial data reported in 1998. In contrast, little change was observed in implicit pro-South attitudes across the 3 different times. The implications of these findings for Korean unification are discussed.On Tuesday, June 13, 2000, the world marked a historic milestone in Korea, the solitary remnant of a world divided by the Cold War. In the North Korean capital of Pyongyang, the President of South Korea, Kim, Dae-Jung, embraced Kim, Jung-Il, the leader of North Korea, before a cheering crowd. The North Koreans waved red flowers as they saluted the symbolic reunion of two brothers who had been separated for over half a century.This first meeting between South and North Korean leaders after the Korean War of 1950-1953 ushered in a new mood of reconciliation and hope for people on both sides of the 38th parallel. Most saw the meeting of the leaders as an initial step in a rapprochement that would culminate in the political unification of the two Korean states.
