The appointment shows Kim is trying to prepare for his eventual departure and pave the way to hand power to one of his sons. Jang is believed to back Kim's youngest son, 26-year-old Jong Un, as successor.
“In a system like North Korea, there is nobody else to trust but one's own flesh and blood,” said Koh Yu-hwan, a professor at Seoul's Dongguk University. “Jang is expected to play a decisive role in strengthening Kim's rule and as a guardian of Kim's successor.”
