As Korea has declared 2020 as ‘the first year of public diplomacy’, the importance of public diplomacy is gradually emphasized in Korean diplomacy of the 21st century. With the chance of the Korea-Africa Forum in 2006 as the turning point of practical relationship, there have been more and more interest in Africa that used to be on the periphery of Korean diplomacy. This year, it has been 14 years after going through total four times of forum. It would be needed to screen Korean diplomacy toward Africa and also public diplomacy. Considering the domestic environment concentrating on the economic interests based on such narrow understanding of Africa, what roles could the public diplomacy expect from Korean policies toward Africa? This study seeks for the answer to this question through cultural approach because the public diplomacy requires the mutual empathy, and in the center of it, there is culture. In Africa, the culture is not the entertainment of daily life, but the order and system. Thus, the public diplomacy should be sought for without violating the cultural elements of Africa. In the aspect of spreading Korean culture and building up the trust relationship, the attitude to actively accept other cultures should be preceded for Korean public diplomacy toward Africa. Otherwise, Africa would strengthen the cultural boundary or Korea would only show the ‘fabricated’ cultural empathy.
