Kang Kyung-hwa, a Senior Adviser on Policy to UN Secretary-General Antonio Guterres, has been appointed the foreign minister, the reports added.
Chung Eui-yong, a former lawmaker and Ambassador to Geneva, was named to head the National Security Office. Since Moon took office on May 10, Chung has been leading a special security advisory group for the new president, according to the outlet.
Moon also picked special advisers for diplomatic and security issues. They are Moon Chung-in, an honorary professor at Seoul's Yonsei University, and Hong Seok-hyun, former Ambassador to the United States, the same outlet added.
According to the reports, the candidacies of the finance and foreign ministers must be confirmed by the parliament, while the appointments of the new presidential officials and advisers are already effective since they are not subject to the parliamentary hearings.
Moon became president after his landslide victory at the snap election on May 9.
