According to the Charter, the UN has four purposes:
To maintain international peace and security
To develop friendly relations among nations
To cooperate in solving international problems and promoting respect for human rights
To be a centre for harmonising the actions of nations
The United Nations is not a world government and it does not make laws. It does, however, provide the means to help resolve international conflicts and formulate policies on matters affecting all of us. At the UN, all the member states, large and small, rich and poor, with differing political views and social systems, have a voice and a vote in this process.
