Jang Jong Nam’s appointment is the latest move since Kim succeeded his late father in late 2011 that observers see as a young leader trying to consolidate control. The announcement comes amid easing animosities after weeks of warlike threats between the rivals, including North Korean vows of nuclear strikes. Pyongyang’s rhetorical outbursts against massive U.S.-South Korean war drills and U.N. sanctions over the North’s February nuclear test were seen, in part, as a push to portray Kim Jong Un at home as a respected military commander on the world stage.

Jang’s new role as minister of the People’s Armed Forces, however, isn’t thought to indicate a potential softening of Pyongyang’s stance toward Seoul and Washington any time soon, analysts said. Jang replaces Kim Kyok Sik, the former commander of battalions believed responsible for attacks on South Korea in 2010 that killed 50 South Koreans. Outsiders don’t know much about Jang, but analysts said it’s unlikely that Kim Jong Un would name a moderate to the post at a time of tension with the outside world.

Mention of Jang’s new role was buried in a state media dispatch listing those who attended an art performance with Kim Jong Un. It’s not known exactly when Jang was formally appointed to the ministerial post.
