Bitterness is growing within China's armed forces to President Xi Jinping's decision to cut troop numbers by 300,000 and considerable effort will be needed to overcome opposition to the order, according to a source and commentaries in the military's newspaper.

Xi made the unexpected announcement on Sept. 3 at a military parade in Beijing marking 70 years since the end of World War Two in Asia. The move would reduce by 13 percent one of the world's biggest militaries, currently 2.3-million strong.

One government official, who meets regularly with senior officers, said some inside the People's Liberation Army (PLA) felt the announcement had been rushed and taken by Xi with little consultation outside the Central Military Commission. Xi heads the commission, which has overall command of the military.
