The country of South Korea has risen on the global stage due to its push for soft power. Soft power refers to a country’s ability to persuade or attract others through its cultural and political values, rather than coercion or military power, which would be considered hard power. One aspect of South Korean soft power that has gained international recognition is South Korean popular music, also known as K-Pop. Since its rise in the early-2010’s, K-Pop has captured the hearts and minds of people world-wide, and it is because of this popularity that has led it to become a frequent subject of interest in the field of global studies and international relations. The globalization of K-Pop and its expansion of Korean culture to the entire world has had an impact on improvements in diplomatic relations between South Korea and other countries. The purpose of this study is to understand how K-Pop artists have contributed to helping South Korea create diplomatic relations with other countries by analyzing three case studies in which K-Pop artists have either performed in different countries to showcase their music and culture or have attended/spoken at international events to represent South Korea and speak on important issues. Through the analysis of these three case studies, we found that the Korean Wave defines South Korean soft power which is why South Korea’s current diplomatic standing is at an all-time high. Furthermore, we found that all foreign engagements made by K-Pop idols will always be imbued with political significance. In conclusion, this study demonstrates how South Korea uses its cultural power, such as K-Pop artists, as a means of building positive international perceptions and strengthening its diplomatic relationships with other nations.
