Korea’s public diplomacy vis-à-vis the US is the centerpiece of the country’s overall public diplomacy policy, with an emphasis on influencing the policy elites in Washington, DC, primarily through think tank-centric activities. This chapter explores Korea’s public diplomacy strategy vis-à-vis the US with an emphasis on the “policy public diplomacy” that was introduced in 2016 – coinciding mostly with the presidencies of Moon Jae-in in Seoul and Donald Trump in Washington, DC. At the policy elite level, the main objective of Korean public diplomacy in the US has been to generate support for Korea’s foreign policies, including in inter-Korean relations; and at the grassroots level, creating more favorability among the general American public. The former is more based on agenda-setting and framing Korean Peninsula-related issues and Korea’s increasing role in global governance. The latter is more diffuse and attempts to increase the country’s visibility and improve its brand value. In this time period, Korean public diplomacy has become partisan for the first time due to dividing nature of emphasis on inter-Korean relations in policy public diplomacy in the US.
