This week, he further consolidated the commission’s role in the power structure, apparently preparing for harsh economic times and uncertain negotiations with the United States.
In a meeting of the Supreme People’s Assembly on Thursday, Mr. Kim was re-elected chairman of the commission, according to North Korean media. He also made one of his most trusted aides, Choe Ryong-hae, first vice chairman of the commission, cementing Mr. Choe’s status as the No. 2 official in the country.
Mr. Choe’s family has been loyal to Mr. Kim’s since the days of Mr. Kim’s grandfather, the North Korean founder Kim Il-sung. This week, Mr. Choe, 69, also replaced 91-year-old Kim Yong-nam as president of the Presidium of the Supreme People’s Assembly, a role that has been equivalent to ceremonial head of state.
But North Korean media reports on Friday referred to the State Affairs Commission chairman — Mr. Kim — as “the supreme representative of all the Korean people,” which led some South Korean analysts to speculate that Mr. Kim had made himself the North’s formal head of state.
Mr. Kim also replaced his country’s premier, who oversees the economy. The outgoing premier, Pak Pong-ju, 80, has been an instrumental figure in the North’s experiment with market-oriented reforms.
To replace him, Mr. Kim chose Kim Jae-ryong, who has built his credentials as party boss of Jagang Province, which is home to many of the North’s munitions factories. The new premier is believed to be in his 60s.
