About the comparison of the European Union and the United Nations
----the different organizational structure
The United Nations is composed of the following bodies :General Assembly（大会）,Security Council（安全理事会）,Economic and Social Council（经济及社会理事),Trusteeship CouThe General Assembly is held once a year (from the third Tuesday of September) to discuss general U.N. functions. Advice is then given to the Security Council based on these discussions. If necessary, an extraordinary general assembly is held.
The Security Council has direct responsibility in maintaining international peace and security. This means that the Council has more authority and power than the General Assembly. The Council is composed of five permanent members (the United States, England, France, China, and Russia) and ten non-permanent members. Non-permanent members are elected by the General Assembly and usually serve for two years. Half of the non-permanent members alternate every year. The permanent members have veto-power, and resolutions need unanimous consent in order to pass.
The Economic and Social Council discusses issues related to international economy, society, culture, and education.
The Trusteeship Council supervises countries under trusteeship in the U.N. trust territories.
The International Court of Justice issues rulings based on the United Nations Charter and International Court of Justice regulations. The judgment of the court is final and cannot be appealed by member states.
The Secretariat serves all administrative functions of the U.N. The Secretary General is nominated at the General Assembly based on the advice of the Security Council.
In addition to these main bodies, there are many subsidiary divisions in the U.N., including the United Nations Educational, Scientific and Cultural Operation (UNESCO) （联合国教科文组织），the International Monetary Fund (IMF)（国际货币基金组织），etc.

The former EC, which formed the core of the EU, originally referred to the group of Western European nations that belonged to each of three treaty organizations—the European Coal and Steel Community(ECSC), the European Economic Community (EEC), and the European Atomic Energy Community(Euratom). In 1967 these organizations were consolidated under a comprehensive governing body composed of representatives from the member nations; further modifications since then have established the institutions of the EU as the European Parliament, the European Council, the Council of the European Union, the European Commission, and the Court of Justice of the European Union, the European Central Bank (see European Monetary System), and the Court of Auditors.
Although the EU has no single seat of government, many of its most important offices are in Brussels, Belgium. The European Commission is headquartered there, as is the European Council and the Council of the European Union; it is also where the various committees of the European Parliament generally meet to prepare for the monthly sessions in Strasbourg, France. The European Central Bank is in Frankfurt, Germany; the Court of Justice and the Court of Auditors are in Luxembourg, Luxembourg。
