North Korea has appointed a new vice defense minister, a report showed Friday, in what appeared to be an ongoing reshuffle of the communist country\'s military personnel. Jon Chang-bok, who was promoted to colonel general in 2010, accompanied North Korean leader Kim Jong-un on a field guidance trip to a food processing plant as the first vice minister of the People\'s Armed Forces, the North\'s Korean Central News Agency (KCNA) said in the report, monitored in Seoul.
