North Korea replaced its hard-line armed forces minister with a relatively \"young\" and unknown field commander, a news report said Monday, in a move that may signal a shift in the country\'s confrontational policies. According to the report by the Korean Central News Agency (KCNA) monitored in Seoul, Jang Jong-nam, in his 50s, was introduced as minister of the People\'s Armed Forces during the Song and Dance Ensemble of the Korean People\'s Internal Security Force that was attended by North Korean leader Kim Jong-un and his wife Ri Sol-ju.
