the South Korean public. South Korea saw another milestone in 2012 with the first ever female president Park Geun-hye elected and assuming office. Daughter of another former president, Park Chung-hee, she carried on a conservative brand of politics. President Park Geun-hye's administration was formally accused of corruption, bribery, and influence-peddling for the involvement of close friend Choi Soon-sil in state affairs. There followed a series of massive public demonstrations from November 2016 and she was removed from office. After the fallout of President Park's impeachment and dismissal, new elections were held and Moon Jae-in of the Democratic party won the presidency, assuming office on 10 May 2017. His tenure saw an improving political relationship with North Korea, some increasing divergence in the military alliance with the United States, and the successful hosting of the Winter Olympics in Pyeongchang.
