The Charter of the United Nations is the foundational treaty of the UN. Some of the principles of the UN Charter are; the association principle, the hierarchy principle, the collective security principle, the regional principle, the mediation principle, the trusteeship principle the judicial principle and the collective security principle.
To be a part of UN, the country either a member or not, should be peace-loving, because, if one of the countries would try to begin hostilities between the UN members or other countries, the purpose of the UN would be marred.
Every country has its own dominance about some topics and according to that the UN have made some countries have more important ubiety than others. By this idea the hierarchy principle has been emerged.
One of the aims of the UN is unlimited growth and prosperity for all and the economic and social council is trying to solve countries’ problems by the help of its seventeen agencies. Some examples are Food and Agriculture Organization (FAO), United Nations Educational, Scientific and Cultural Organization (UNESCO) and International Atomic Energy Agency (IAEA).
The charter decided that the nations should not form other organizations between them, because this could impair the association between the members of UN.
Another important aim of the UN is to keep the peace between the adversaries and help them to solve their problems by acting as the mediator.
