Despite the large number of contributors, the greatest burden continues to be borne by a core group of developing countries. The 10 main troop-contributing countries to UN peacekeeping operations as of June 2004 were Pakistan, Bangladesh, Nigeria, Ghana, India, Ethiopia, South Africa, Uruguay, Jordan and Kenya. About 10 per cent of the troops and civilian police deployed in UN peacekeeping missions come from the European Union and one per cent from the United States.
The largest contributers were from Pakistan (8,652), Bangladesh (8,211) and Nigeria (3,577). The biggest contributer from a western country is Poland with 739 peacekeepers on a 19th place. The USA ranks 26th with 430 peacekeepers. The EU combined have 4,532 peacekeepers.
