North Korean leader Kim Jong Un's sister has suggested that if South Korea abandons its hostility, the two countries could discuss improving relations.
Kim Yo Jong issued a statement through the North's state-run news agency on Friday.
She was responding to a speech by South Korean President Moon Jae-in in which he reiterated his calls for a declaration to formally end the Korean War.
Moon told the UN General Assembly on Tuesday that "peace on the Korean Peninsula begins always with dialogue and cooperation."
In her statement, Kim called the end-of-war declaration "an interesting and an admirable idea" in terms of putting an end to the "instable state of ceasefire" on the Korean Peninsula and "to withdraw hostility toward the opposite party."
She said that if South Korea is "careful about its future language and not hostile" toward the North, Pyongyang is willing to keep its "close contacts with the south again and have constructive discussions with it about the restoration and development of the bilateral relations."
Earlier on Friday, North Korea's Vice Foreign Minister Ri Thae Song issued a statement also urging the United States and South Korea to withdraw their hostile policy.
