TEHRAN, Young Journalists Club (YJC) - The North's official KCNA agency said Ri accompanied Kim on his visit to a war veterans' cemetery as the army's chief of general staff, marking the 65th anniversary of the armistice agreement that ended the 1950-53 Korean War.
Ri formerly held the four-star position before he was briefly demoted deputy chief and three stars for an unspecified reason in 2016.
His return adds the recent appointments of No Kwang Chol, first vice defense minister, as the defense chief, and Army General Kim Su Gil as director of the military's powerful General Political Bureau.
All of the newly promoted officials are younger than their predecessors, even though they are all in their 60s. Ri is 63 years old, 21 years younger than his predecessor, Ri Myong Su.
