SEOUL—South Korea predicted on Tuesday that North Korea would look to open negotiations with the United States next year in an optimistic outlook for 2018, even as Seoul set up a specialized military team to confront nuclear threats from the North.
The U.N. Security Council unanimously imposed new, tougher sanctions on reclusive North Korea on Friday for its recent intercontinental ballistic missile test, a move the North branded an economic blockade and act of war.
