Seoul is bracing for the possibility that North Korea and the U.S. may declare a formal end to the Korean War at their upcoming summit in Hanoi, the South Korean presidential office said on Monday, emphasizing that such a bilateral-level declaration would be “sufficient.”

Presidential spokesperson Kim Eui-keum admitted the possibility when asked if the declaration of the end to the Korean War could be a topic of discussion at the second DPRK-U.S. summit, set to begin February 27 in Vietnam.
