Background & Analysis

Kim Yo Jong, is the sister of Kim Jong Un Supreme Commander of the Democratic Peoples Republic of Korea.  It is thought Yo Jong is in her 30s, and was born in 1988.  Her Parents are Kim Jong Il the late leader of North Korea and his consort, professional dancer Ko Yong Hui.  It is uncertain if Yo Jong is married, however some sources believe she is married to Choe Song, son of a powerful official in the North Korean hierarchy.  Choe Song is rumored to work for the intelligence unit known as Office 39, alternatively it is speculated he is an elite military body guard that provides security for the Kim Jong Un.  Yo Jong attended school in Switzerland with her brother Kim Jong Un, using secret identities.  It is during their time in Switzerland that analysts believe Yo Jong & Kim Jong Un developed a powerful bond and learned to trust each other with complicity.  Between 2000 & 2007 there are gaps as to the whereabouts and activities of Kim Yo Jong.  Kim Yo Jong graduated from university in Pyongyang with a degree in political science, commenced activity in the Workers Party of Korea in 2007 and became her brother’s political ally in 2008.  The first time Yo Jong made a public appearance was at her father’s funeral, Kim Jong Il in 2011.  Her existence was barely known to the wider world until the funeral, when she was seen standing right behind Kim Jong Un on state television, looking tearful and ashen-faced.  Kim Yo Jong is now seen as one of the most powerful women in North Korea.  Her portfolio includes, Head of the Propaganda Department of the Workers Party of Korea, and a member of the countries Politburo (North Koreas Communist Party).  Her responsibilities include, policy, high level intelligence briefings, and logistical support for her brother’s public profile events.  Kim Yo Jong is known as the “Gatekeeper” to her brother Kim Jong Un.  She is Kim Jong Uns closest aid and is one of his top 20 officials.  Kim Yo Jong took charge of North Korea in 2014 when Kim Jong Un was reported as ill with gout or diabetes.  Yo Jong found her voice in 2020, in her first public statement she insulted South Korea “as a frightened dog barking” after South Korea condemned North Korean military live fire drills, and called North Korean defectors spreading anti-Pyongyang leaflets “human scum little short of wild animals and mongrel dogs,” threatening South Korea for allowing the leaflets to be disseminated.  Yo Jong has demonstrated her power and authority when she recently ordered the North Korean military to deploy troops to two joint economic projects with South Korea — the Mt. Kumgang tourist area and the Kaesong Industrial Zone.  In a show of force in June of 2020 Kim Yo Jong ordered the department in charge of inter-Korean affairs to “decisively carry out the next action” which resulted in the explosive demolition of the inter-Korean liaison office in North Korea’s Kaesong Industrial Complex.  It is now quite clear that Kim Yo Jong is a powerful and influential leader, capable of running North Korea with a firm hand and decisive actions.  It remains to be seen who will step into the shoes of Kim Jong Un in the event of his death, however it appears Kim Yo Jong has the aptitude, intelligence and ruthlessness required to continue the Kim family dynasty.

It looks like there is this kind of power partnership between the two that became more visible (CNBC, 2020)

Why is Kim Yo Jong a Serious Contender for Leadership of North Korea DPRK?

  • Leadership has always been a family affair in the North, and she is now one of the most prominent members of the “Paektu bloodline” — a Northern term for Kim Il Sung and his descendants, who have led the nuclear-armed country since its foundation
  • “She is, as best we can tell, a very capable and high-skilled member of the North Korean leadership—and is not one to be underestimated by any stretch of the imagination,” Harry J. Kazianis, senior director of Korean Studies at the Washington D.C- based think tank the Center for the National Interest (Time, 2020)
  • Experts have agreed that Kim Yo Jong’s recent tactics have cemented her reputation within North Korea as a strong and decisive leader who could replace her brother if necessary. “As she leads the offense against South Korea like a general, it silences those old hard-liners in the Politburo who may think she cannot be the leader,” Sejong Institute analyst Lee Seong Hyon told The New York Times (Business Insider, 2020)
  • Kim Yo Jongs public profile is mounting rapidly and she has been mooted as a potential successor (Hindustan Times, 2020)



Why Might Kim Yo-Jong Not Succeed as the Next Leader of DPRK?

  • “It’s definitely possible that she would face some serious challenges to her legitimacy and power if she took over, even with the Kim family name,” Mintaro Oba, a former U.S. State Department official who specialized in the Korea’s (Time, 2020)
  • Scott A. Snyder, senior fellow for Korea studies and director of the U.S.-Korea policy program at the Council on Foreign Relations, tells TIME that since the recognized line of succession in the Kim dynasty is father-to-son, Kim might serve “as a sort of regent and de facto leader in the absence of a viable successor” (Time, 2020) (North Korea Leadership Watch, 2009)
  • Although details about Kim Jong Un’s family are closely guarded, some believe that Kim Jong Un may have a young son who could take over when he is old enough
  • Another possible successor is Kim Pyong Il, who is Kim Jong Un’s uncle (Kim Il Sung’s son and Kim Jong Il’s half-brother). Despite spending 40 years overseas as a foreign diplomat, he reportedly remains popular in the country owing to a resemblance to Kim Il Sung
  • Lami Kim, a former South Korean diplomat and fellow at the Wilson Center says that there is much speculation over why he returned to North Korea last year. “One scenario is that Kim Jong Un has been concerned about his own health and what would happen to his family and the regime should he die,” she says. “So perhaps he recalled his uncle either to succeed him, or to help Kim Yo Jong run the country” (Time, 2020) (CNBC, 2020) (North Korea Leadership Watch, 2009)
