There, at the end of a day of remarkable diplomacy, was the president of South Korea, Moon Jae-in, as well as Kim Yo Jong, the sister of North Korean leader Kim Jong Un and one of his closest advisers.
The two sides stressed on Saturday that they were interested in maintaining movement toward peace. But it would be Kim's first meeting with a foreign head of state.
Pence did not directly address news of the invitation when asked.
The South's Unification Ministry said steps to improve ties would be led by the two Koreas, but with the support of the worldwide community.
Its most famous alumna is Ri Sol Ju, better known these days as the First Lady of North Korea. Since he took power six years ago, he has not only executed scores of senior party officials and military generals but also rattled the region by accelerating nuclear and missile tests. His single-minded pursuit of a nuclear arsenal to counter what he sees as the threat of invasion by the United States has ratcheted up tensions not only with his rivals but also with primary trading partner China and with Russian Federation, once a key benefactor.
Apart from their official activities, it is unlikely the women will have much interaction with South Koreans or freedom to explore their surroundings.
The agreement was seen as a breakthrough, given the Koreas had not marched together at an Olympics for more than 12 years.
Amid Olympic thaw, Pence says allies united in isolating North Korea
In response, the Kim regime may resume testing its nuclear and missile programs, as it has done after past Olympic détentes. He pointedly did not, though at once point he and Kim You Jong sat just feet from each other, and maybe it's just as well.
The charity's statement comes after the joint Korean women's ice hockey team and the pro-unification flag show.
U.S. Defense Secretary Jim Mattis said on Sunday it was too early to tell whether a diplomatic detente between the two Koreas at the Winter Olympics would lead to results, but the move had not driven a wedge between Washington and Seoul.
"Now, if we put our hearts and minds together, it will continue to grow larger and larger and turn into a snowman of peace".
Her brother - the third generation of her family to rule the isolated and impoverished North - will be pleased with her global diplomatic debut, said Yang Moo-jin, professor at the University of North Korean Studies at Seoul.
Kim Yo Jong, the sister of the North Korean leader Kim Jong Un, made some highly anticipated, heavily publicized appearances during the Olympic opening ceremonies in Pyeongchang.
But she had no hesitation about attending the Olympics, because she looks around and sees her South Korean neighbors utterly calm. Almost 200 female members of the North Korean cheerleading regime - a handpicked group created to be an appealing propaganda arm of the ruling party - chanted and sang (and did the wave on several occasions) while other fans clapped along in between Switzerland's offensive barrages. The official added that Pence does not believe that the invitation dilutes the toughness of the United States pressure campaign on North Korea. The article reiterated that the North's decision to send delegates to the South had nothing to do with an attempt to approach the United States for talks.
But both sides have held their ground.
Until now, the Trump administration had laid out a strategy called "maximum pressure", whereby the USA and its allies use all possible tools to make life hard on North Korea, forcing them to agree to denuclearize and agree to talks.
