With 2.3 million active troops, the People's Liberation Army (PLA) is the largest military in the world.[81] The PLA consists of an army, navy, air force, and strategic nuclear force. The official announced budget of the PLA for 2009 was $70 billion. However, the United States claims China does not report its real military spending. The DIA estimates that the real Chinese military budget for 2008 could be anywhere from US$105 to US$150 billion.[82]
