The elder Mr. Kim also appointed his sister KimKyongHui, 64 years old, who long shunned the spotlight, as a four-star general and to political posts in the party.
He is a close associate of Kim Jong Eun's aunt KimKyongHui and uncle Jang Song Thaek and had gradually moved back into more senior roles over the past few years.
KimKyongHui has held a series of positions in economic ministries and agencies and, before a revaluation of the country's currency in 2009, published articles about the need for the government to curtail market-oriented activity.
