Former United Nations Secretary-General Ban Ki-moon confirmed that he won't be running for president of South Korea. After returning to South Korea, he said an overhaul of the political system is necessary ahead of the election later this year. “I was very disappointed by some politicians’ obsolete and narrow-minded behavior. Reflecting on this, I decided to abandon my pure will to take a lead in changing the politics and uniting the nation," Ki-moon told reporters in Seoul. Earlier in the year, Ban’s brother and nephew were charged by U.S. prosecutors due to a bribery scheme regarding a skyscraper complex in Vietnam. It is believed that Moon Jae-in, Ban's key opponent, will lead the country's elections.
