김여정
According to Kim Yong-hyun, a professor of North Korean studies at Dongguk University in Seoul, and others, the promotion of Kim Yo-jong and others is a sign that "the Kim Jong-un regime has ended its coexistence with the remnants of the previous Kim Jong-il regime by carrying out a generational replacement in the party's key elite posts". Tom O'Connor of "Newsweek" echoed this opinion, writing that Kim Yo-jong's rise to power was part of Kim Jong-un's overall plan to appoint younger people in place of his father's older elites who may have harboured doubts about the younger Kim Jong-un's ability to lead North Korea.
