President Donald Trump shares a toast during a state dinner hosted by South Korea’s President Moon Jae-in at the Blue House in Seoul, South Korea November 7, 2017.
During a speech delivered in South Korea last week, Trump called North Korean leader Kim Jong Un a “tyrant.” Kim’s government responded by calling Trump an “old lunatic.”
Ban believes the only way to deal with North Korea is through diplomatic means.
“There is no military solution,” he said. “Military means sometimes may be effective for a time being but it’s not sustainable. You have seen such cases in Iraq and Afghanistan and in Syria.”
He is also optimistic that the sanctions against North Korea are working.
Chinese President Xi Jinping “has made it clear that they will faithfully implement the Security Council resolution, and it seems that they are now doing it. That’s why North Korea recently has been criticizing China by calling them names,” he said. “That means the sanctions seem to be working.”
