Kim Yo Jong sat beside her older brother, North Korean leader Kim Jong Un, as the only woman among six delegates as Friday's historic inter-Korean talks got underway.

While she diligently took notes as her brother spoke and sought no moment in the spotlight, the 30-year-old has been widely seen as instrumental in making the summit happen.

It was Kim, as the first member of the North's ruling dynasty to visit the South since the Korean War ended in an armistice in 1953, who delivered a message to the South for a desired detente at the Olympics.

And it was Kim who personally delivered a letter on her brother's behalf to South Korean President Moon Jae-in, as communications resumed between the nations.

Kim's profile has been steadily rising since 2014, when she given the key regime role of deputy director of the Propaganda and Agitation Department of the Workers' Party.

Kanye West Has Had 'Explosive' Fights with Kris Jenner & Kim Kardashian Can't 'Control' Him: Sources

The last week has been a difficult one for the Kardashian-West family. According to multiple sources, Kanye West has cut off contact with multiple people in his inner circle, including his managers, lawyers and closest friends — and he’s also had multiple rows with his mother-in-law Kris Jenner. “He’s had huge blow-ups with Kris. She sees how erratic he’s acting and is most concerned about her daughter’s brand. She’s also trying to be a good mother-in-law, so he’s having explosive issues with her too,” a source close to the situation tells PEOPLE exclusively. “Everyone is really, really worried.” A rep for the Kardashians and the Jenners did not immediately return PEOPLE’s request for comment. The rapper returned to Twitter but has been posting tweets that are increasingly worrisome to some of his loved ones. In one recent tweet, West suggested the need to “get rid of everything.” Sometimes you have to get rid of everything— KANYE WEST (@kanyewest) April 17, 2018 WaitEVERYTHING?!?!?! ??????????? https://t.co/0wrL1c0shB— Kim Kardashian West (@KimKardashian) April 18, 2018 A source close to the rapper contends that while West can be “eccentric and erratic,” not everyone sees his latest actions as cause for concern. Says the source: “A lot of this is just Kanye. He’s always been like that. He stirs the pot.” Kardashian West playfully responded to her husband on social media, but the source close to the situation says it was an attempt to take charge.

Kim Jong Un's 'gatekeeper'

But Kim's acts of public diplomacy are highly choreographed, and, like most members of the Kim clan, little is definitively known about her or her motivations, beyond her official duties.

She is believed to be the youngest of seven siblings their father, Kim Jong Il, had with four women.Many of them are half-siblings, but Kim shares the same mother with the North Korean leader.

Kim was always close to her father, and after returning from Switzerland she was appointed to positions of responsibility in the government, according to Michael Madden, who runs the blog North Korea Leadership Watch.

She would act as an advance-team leader, inspecting sites before official visits and taking on administrative duties.

Under her brother's leadership, Kim has taken on more responsibility, dealing with policy, receiving intelligence briefings and acting "almost like a White House chief of staff would," said Madden.

She was promoted to the country's Politburo, the senior body of North Korea's communist party, as an alternate member last year. According to North Korea Leadership Watch, she is a close aide of her brother's "and since his accession manages his public events, itineraries and logistical needs, among other tasks."

She is now among her brother's top 20 officials, and is seen as something of a gatekeeper to the leader, according to analysts.

"She's probably one of the most influential people on Kim Jong Un himself, precisely because he has very few people he can trust," said Balbina Hwang, visiting professor at Georgetown University and founder of the National Committee on North Korea.
