Radio Sputnik discussed the significance of the meeting with Tong Zhao, a fellow at the Carnegie-Tsinghua Center for Global Policy in Beijing.
"I think in the first period we were nervous and it's hard to come back from that", she said.
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".
In the meeting, Kim Yo Jong handed Moon a letter from her brother, and she asked Moon to visit the North at the earliest possible date for an inter-Korean summit. US President Donald Trump was threatening to bring "fire and fury" on the heads of North Koreans, the United Nations was passing increasingly tough sanctions while Hawaii got a small taste of what the beginning of a nuclear war might look like with a false incoming ICBM alert.
The DPRK delegation also included Kim Yo Jong, Kim Jong Un's younger sister who serves as the first vice director of the Central Committee of the ruling Workers' Party of Korea.
"Dizzying" is how one South Korean newspaper described the diplomatic typhoon swirling over the Korean Peninsula, with all the big players seemingly wanting different things and Moon, at times, the only calm in the storm.
Some in the arena were apparently taken aback by the North Korean cheerleaders - the special squad sent by the North Korean leader - who continued to sing and sway in unison while drowning out music performed by South Korean numbers on a nearby stage. How much do the Olympic Games contribute to the relations between the two neighboring countries?
"We know that Western media are planning pseudo-investigations on the theme of "Russian fingerprints" in hacking attacks on information resources related to the hosting of the Winter Olympic Games in the Republic of Korea", Russia's foreign ministry said.
Tong Zhao: Oh, absolutely. "Moon should be aware that he has to urge denuclearisation to North Korea by himself, not depending on dialogue between the US and North Korea", an editorial in the Yomiuri Newspaper read.
The discarded grid girls of Formula One and the defunct women of darts might consider relocating to North Korea.
A senior Japanese defence official said North Korea's Games charm offensive could "simply be a way to gain time" until it completed its nuclear and ballistic missile development.
A White House official described the South Korean president as hopeful that there would be "some talks and socializing" between Pence and the North Koreans over the course of the weekend. He supported Pence's moves to meet with North Korean defectors, paying respects at a memorial to the 46 South Korean sailors killed in a 2010 torpedo attack blamed on the North. Pence also invited as his Olympics guest the father of USA college student Otto Warmbier, who died after he was imprisoned by North Korea for stealing a propaganda poster. How likely is this resumption at this point?
On Saturday, the North's delegation paid a visit to Moon at the presidential office Cheong Wa Dae. Of course, if North Korea moves forward with new provocations - such as missile or nuclear tests - all bets are off.
That's the precondition for the United States talking with North Korea, and all the signals so far we've seen from Washington are very stubborn.
Washington has long insisted the North must show a willingness to denuclearise before any negotiations - which Pyongyang says it will never do. "Some may argue that a transition to a new world order is already underway, and the United States would eventually have to yield simply because time is on North Korea's side".
