Kim Yo Jong gave a personal letter from her brother Kim Jong Un to South Korean President Moon Jae-In
North Korea's state news agency said on Sunday its delegation sent to the Winter Olympics held "frank and candid" talks with South Korean President Moon Jae-in but there was no mention of the North's invitation to Moon to Pyongyang for a summit.
The delegation, the highest-ranking to visit the South, concludes its visit later on Sunday having charmed and intrigued the South Korean public, but still faces deep scepticism over the North's sincerity towards improving relations.
Any summit between the two still-officially warring Koreas would be a coup for Moon, who has been pushing for a diplomatic solution to the standoff over North Korea's nuclear and missile programmes.
Kim Yo Jong, the younger sister of Kim Jong Un, "courteously" handed over a personal letter from the North Korean leader to Moon during talks on Saturday and also told Moon of her brother's "intention", KCNA said, without elaborating on what that was.
South Korean officials have said Moon was invited to Pyongyang to speak with Kim Jong Un during the talks and lunch that Moon hosted at the presidential Blue House in Seoul on Saturday.
Such a summit, if it came about, would mark the first time that leaders of the two Koreas have met since 2007.
U.S. Vice President Mike Pence, who has left South Korea for Washington, said the United States, South Korea and Japan were in complete agreement on isolating North Korea over its nuclear weapons programme.
"There is no daylight between the United States, the Republic of Korea and Japan on the need to continue to isolate North Korea economically and diplomatically until they abandon their nuclear and ballistic missile programme," Pence told reporters during the return flight to the United States.
A White House official said that, although Moon did not discuss the invitation with Pence on Saturday, the South Korean president made it very clear that only when North Korea actually starts to take steps to denuclearise would anyone even consider beginning to take the pressure off.
EARLIEST CONVENIENCEAccording to the Blue House, Kim Jong Un wanted to meet Moon "in the near future" and would like for him to visit North Korea "at his earliest convenience", his sister told Moon.
The South Korean leader said in response "let's create the environment for that to be able to happen", Blue House spokesman Kim Eui-kyeom told a news briefing.
The KCNA report cited Moon as saying inter-Korean relations should be mended by the parties concerned "at any cost as indicated by Chairman Kim Jong Un in his New Year Address".
Kim Yong Nam, the North's nominal head of state who was also at Saturday's meeting, said "even unexpected difficulties and ordeals could be surely overcome and the future of reunification brought earlier when having a firm will and taking courage and determination to usher in a new heyday of inter-Korean relations".
However, South Korea's main opposition party warned any talks between the two Koreas where the scrapping of North Korea's nuclear programme was not a precondition would only "benefit the enemy".
"We should firmly keep in mind any talks where denuclearisation is not a precondition only buy North Korea more time to complete its nuclear capabilities while they fool us with their peace offensive facade," said Chang Je-won, spokesman for the Liberty Korea Party.
Japanese editorials sounded a similar warning, saying dialogue would be meaningless unless it led to denuclearisation of the Korean peninsula.
"What cannot be overlooked is that Moon did not directly demand North Korea to abandon its nuclear development,Moon should be aware that he has to urge denuclearisation to North Korea by himself, not depending on dialogue between the U.S. and North Korea," an editorial in the Yomiuri Newspaper read.
The North Korean delegation was invited to lunch with South Korean Prime Minister Lee Nak-yeon at the five-star Walkerhill Hotel in eastern Seoul on Sunday, an official at the prime minister's office told Reuters.
