North Korea has replaced its coal minister, apparently after the shock execution of leader Kim Jong-un's uncle, who had been accused of attempting to take control of the country's lucrative coal export business.
Pyongyang's state-run Korean Central News Agency introduced Mun Myong-hak as "minister of coal industry" as it was reporting on the 30th anniversary of the Pukchang area coal-mining complex in the western province of South Phyongan yesterday.
The last time the North's coal minister was mentioned in the country's state media was a year ago, when Rim Nam-su was in office.
The shock purge and execution of Jang Song-thaek, the once-powerful uncle and political regent to young leader Kim Jong-un, was sparked by his attempts to take over the North's coal export industry, South Korea's spy chief Nam Jae-joon said last month.
The moves by Jang contributed to the North's economic troubles, Kim Jong-ha, chief secretary of the cabinet secretariat said last month in an interview with the Choson Sinbo, a pro-Pyongyang newspaper in Japan.
The report also indirectly confirmed that Kim Jong-ha had replaced Kim Yong-ho following Jang's downfall. It is not known what became of Kim Yong-ho or Rim Nam-su.
Last week, Pyongyang's Chosun Chungang TV introduced Kim Yong-kwang as the new minister of metal industry.
"Probably, these are all part of a government reshuffle related to Jang's purge," said Chang Yong-seok, senior researcher at the Institute for Peace and Unification at Seoul National University.
Further changes affecting higher posts including those at the powerful National Defence Commission (NDC) were likely to come in April when the North's rubber-stamp parliament opens, he said.
Jang was one of the deputy chairmen at the NDC, which is currently chaired by the young leader.
Kim Jong-ha said North Korea would move to independently produce and reprocess coal and other natural resources for export. "The cabinet will fulfil its function properly as a control tower of the economy," he said, adding that it was trying to regain control over projects.
The impoverished North has sought for years to bolster its crumbling economy by increasing exports of minerals.
A military court that handed Jang a death sentence found him guilty of "committing such acts of treachery as selling off precious resources of the country at cheap prices", according to Pyongyang's state media.
