Sung Kim, the new U.S. special envoy to North Korea, will only fulfill his role on a part-time basis, multiple informed sources confirmed to NK News on Wednesday. His main job will continue to be U.S. Ambassador to Indonesia, based in Jakarta.

It had been assumed by many that Kim would be primarily focused on the North Korea portfolio. South Korean President Moon Jae-in described Kim’s unexpected appointment as a “surprise gift” over the weekend, and American and South Korean media described Kim as the former U.S. ambassador to Indonesia shortly after his new role was announced.
