A former deputy chief of the army’s general staff, Lt. Gen. Wei Fenghe, has been promoted to commander of the Second Artillery Corps, home of the strategic missile force, the Defense Ministry said Monday. The new position, as head of one of China’s most important military units, is part of a major turnover in China’s armed forces and almost certainly assures General Wei a seat on the Central Military Commission, the military’s top decision-making body. The commission will oversee the rapid modernization of China’s military.
