North Korea's senior leadership left South Korean President Moon Jae-in with a diplomatic conundrum, and his decision could prove to be a defining moment for his leadership - whether to accept an invitation to Pyongyang for talks with his North Korean counterpart, who presides over a nation where opposition is brutally suppressed, senior officers face execution if they stand in his way and even his own family members are eliminated if they are perceived to pose a threat to his power.
Moon responded in a noncommittal way, saying that he wanted to "create the environment for that to be able to happen".
Moon would like to bring both North Korea and the United States to the negotiating table.
Pence spent the days leading up to the games warning that the North was trying to "hijack the message and imagery of the Olympic Games" with its "propaganda". The two Koreas had combined teams and played simply as "Korea", wearing uniforms emblazoned with blue-and-white flags showing an undivided peninsula.
At an earlier dinner with senior Seoul officials, Kim Yo Jong said she found the two Koreas still had much in common despite decades of separation.
Korea, ranked 22nd in the world, nearly took a surprise lead when Han Soojin's shot hit the crossbar in the first period but never looked like threatening after that against the side now ranked sixth in the world.
"I think they were nervous", Murray said.
Many experts say Kim's overture is meant to use improved ties with Seoul as a way to weaken US -led worldwide sanctions toughened after its series of big weapons tests past year that include its sixth and largest nuclear test explosion and three intercontinental ballistic missile launches.
"The vice-president is grateful that President Moon reaffirmed his strong commitment to the global maximum pressure campaign and for his support for continued sanctions", Pence spokeswoman Alyssa Farah said when asked about the development.
During his swearing-in ceremony previous year, Moon said he would be willing to travel to Pyongyang "under the right conditions", and that "for peace on the Korean Peninsula, I will do everything that I can do". Kim Yo Jong is 28 years old, according to the USA government.
The show was the final set-piece element of the North Korean delegation's landmark visit, the diplomatic highlight of the Olympics-driven rapprochement between the two halves of the peninsula, before the North Koreans flew home. The North Koreans have invited Moon to visit Pyongyang in what would be the third inter-Korean summit talks since their 1945 division.
If "diplomatic dance" were an event at the Winter Olympics, Kim Jong Un's younger sister would be favored to win gold. "It will be hard for the allies to resume their military exercises during summit planning".
Pence did say, however, that Moon shared with him details of his meeting with North Korean leaders, without elaborating. The left-wing Kyunghyang newspaper called the actions "deeply disrespectful". North Korea has jumped at the opportunity.
The north's state-run agency said the talks were "warm" but added they were "frank and candid".
But the vice president's team saw it differently.
There were South Koreans who agreed with Pence's stance.
The Trump administration will now talk to Kim Jong Un's regime without preconditions.
Regardless of the different perspectives, Saturday was a remarkable day historically.
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.
The catalyst for her visit was the Winter Olympics, which Moon is promoting as the "peace games".
The North initially had no athletes coming to the Olympics, but the International Olympic Committee allowed 22 as special entries.
In South Korea and beyond, commentators are taken with Kim's surprisingly stylish and relaxed demeanor.
Mattis' remarks come after South Korean President Moon Jae-in was presented a formal invitation to visit North Korea, potentially setting up the first meeting of Korean leaders since 2007. "And it also is a signal that North Korea is not this insane, weird former Cold War state - but it too has young women that are capable and are the future leadership".
However, the statement made no mention of Mr Kim's invitation to Moon to a summit "at his earliest convenience". But it would be Kim's first meeting with a foreign head of state.
Pyongyang conducted its largest nuclear test past year and in November tested its most advanced intercontinental ballistic missile that experts said has the range to reach anywhere in the United States.
Born in 1987, she studied in Switzerland, like Kim Jong Un, and is believed to have attended Kim Il Sung University and a European school for her higher education.
