[Aljazeera] North Korea sees little use in maintaining a personal relationship between leader Kim Jong Un and United States President Donald Trump if Washington sticks to hostile policies, state media reported on Friday - two years after the two men held their first summit.Policies from the US prove Washington remains a long-term threat to the North Korean state, and its people and North Korea will develop more reliable military forces to counter that threat, Foreign Minister Ri Son Gwon said in a statement carried by state news agency KCNA.
