China deploys about 2,150 military and police personnel in UN peacekeeping missions in 10 countries, more troops and police than the US, UK and Russia combined. But China has refused to lend support to NATO-led missions, such as the war in Afghanistan, and denied a group of Mongolian trainers passage through China en route to Afghanistan in October 2009 until ammunition was taken off the plane.
