Choe Ryong Hae has lost some of Kim Jong Un’s confidence due to his arrogance as Hwang Byong So advances into the Presidium of the Politburo, a South Korean expert said.

Still, based on his public appearances and mentions, Choe continues to retain some importance in the party, the Sejong Institute’s director of the unification strategy studies program Cheong Seong-chang said in an interview with Voice of America on Monday.

“While Hwang Byong So has a good reputation among the leadership, Choe is known to … have aggravated relations with other elites with his arrogance and blaming others,” Cheong said.
