By developing hypersonic weapons and testing them before the presidential changeover in the United States, North Korea has a significant bargaining chip to use for whenever the new Trump administration comes looking to continue their previous diplomacy with Kim Jong-un.

North Korea has fired what appears to be an intermediate range ballistic missile towards the sea to its east, South Korea's military said, in what is Pyongyang's first missile launch in two months. Japan's defence ministry said around noon local time (03:00 GMT) that the projectile had already fallen into the sea.
