North Korea must earn its way back to the table: Rex Tillerson

United States Secretary of State Rex Tillerson has told the United Nations Security Council that North Korea must cease all threatening behaviour before talks with the US can begin. This as a steep denial to his earlier offer of talks without preconditions, earlier. He had said he was willing to start talks with Pyongyang without preconditions, which the White House refuted and said they were caught off guard by his offer.
