South Korea's National Intelligence Service (NIS) is actively investigating whether North Korean leader Kim Jong Un has a son, while maintaining that his teenage daughter remains the likely successor to the nation's leadership. The NIS stated Thursday that even if a son exists, he would not be in a position to inherit power from Kim, who assumed leadership following his father's death in 2011.
The agency reaffirmed its assessment that Kim's daughter, reportedly named Kim Ju Ae and approximately 13 years old, is in line to succeed her father. The NIS indicated it is still working to verify reports of an elder brother but concluded that such a son, if he exists, cannot be the heir under current circumstances. A younger child whose gender is unconfirmed also exists.
This statement appears to address recent media reports suggesting that South Korean intelligence authorities have determined Kim has no son with his wife, Ri Sol Ju. The NIS's assessment of Kim Ju Ae's strong political standing is reportedly based on her public appearances and the state protocols afforded to her.
Since late 2022, Kim Ju Ae has been a prominent figure alongside her father at significant state events, including missile tests and military parades. North Korean state media has highlighted her as Kim's "most beloved" or "respected" child, showcasing their close relationship and her growing public profile.
Previous reports have offered conflicting information. In 2023, a South Korean lawmaker stated the NIS had informed a legislative committee that Kim Ju Ae had an older brother. However, the agency reportedly clarified at the time that it was still attempting to verify claims of a son.
The question of whether Kim Ju Ae has an older brother is a critical point in discussions about North Korea's succession plans, given the country's patriarchal system and male-dominated power structure. All three of North Korea's leaders since its founding in 1948 have been men from the Kim family: Kim Jong Un, his father Kim Jong Il, and his grandfather Kim Il Sung.
Some analysts express skepticism about the potential acceptance of a female leader by North Korea's aging elite. Concerns have also been raised that Kim Ju Ae's ascent could ultimately challenge her family's dynastic rule if she were to marry outside the family and pass power to her own children. Other experts suggest that Kim Jong Un, who is 42, may be too young to formally designate an heir, as such a move could potentially dilute his absolute authority.
