North Korea has revealed that leader Kim Jong Un's sister has been named as a senior official in the ruling Workers' Party, strengthening analysts' views that she is an increasingly important part of the family dynasty that runs the country.
State media on Thursday referred to Kim Yo Jong as a departmental vice director within the party's Central Committee.
Analysts said the mention could signal the growing role of Kim's younger sister in supporting her brother's authoritarian rule. The siblings' late father, former leader Kim Jong Il, was seen as relying on his own sister during his 17-year rule.
Outsiders closely study North Korea's opaque ruling power dynamics for clues about a secretive country that pursues nuclear weapons and threatens its neighbours with war.
The Korean Central News Agency first referred to Kim Yo Jong as a senior official in the Central Committee in March, but this is the first time state media have specified her role.
Yang Moo-jin, a North Korea expert at the University of North Korean Studies in Seoul, said a departmental vice director is roughly equivalent to a vice Cabinet minister.
The announcement of Kim Yo Jong's role shows that the government is now confident enough to introduce her as an important part of its leadership, Yang said.
Since taking over North Korea's leadership following the death of his father in 2011, Kim Jong Un has removed key members of the old guard.
The process was highlighted by the 2013 execution of his uncle, Jang Song Thaek, the husband of Kim Jong Il's influential sister.
Jang, who was once considered the second most powerful man in North Korea, was accused of treason.
Kim Jong Un's most influential advisers now appear to be Choe Ryong Hae, the secretary of the party's Central Committee who recently visited Russia as a special envoy, and Hwang Pyong So, vice marshal of the Korean People's Army.
