When people ask “What are the 5 main UN countries?”, they are usually referring to the five permanent members of the United Nations Security Council, commonly known as the P5. These countries are China, France, Russia, the United Kingdom and the United States.
The five permanent members have a special position within the UN Security Council because each has the power to veto substantive decisions. The Security Council has 15 members in total: five permanent members and ten non-permanent members elected by the General Assembly for two-year terms.
The five permanent members are:
These countries became permanent members when the UN Security Council was established under the UN Charter in 1945.
The term “main UN countries” is informal. The five countries are not more important than the other 188 UN Member States in terms of general UN membership. All 193 UN Member States are represented in the General Assembly and have the right to participate in its work.
The P5 have a particularly powerful role because of their permanent seats on the Security Council.
The Security Council is the UN organ with primary responsibility for maintaining international peace and security. Unlike the General Assembly, which includes all UN Member States, the Security Council has only 15 members.
The five permanent members hold their seats indefinitely, while the ten non-permanent members are elected for two-year terms.
The Council can consider conflicts, international security crises, sanctions, peacekeeping operations and other threats to international peace.
The UN Security Council veto allows any of the five permanent members to prevent the adoption of a substantive draft resolution by voting against it.
This means that even if a majority of Security Council members support a proposal, a negative vote from any one of the five permanent members can prevent its adoption when the veto applies.
This is one of the most controversial features of the UN system. Supporters argue that the veto reflects the geopolitical realities of the countries that played a central role in establishing the post-World War II international order. Critics argue that it can prevent the Security Council from taking action in major international crises.
They have significant institutional power, particularly within the Security Council, but calling them the “five most powerful UN countries” can be misleading.
The United Nations has 193 Member States, and the General Assembly provides universal representation. Each Member State has one vote in the General Assembly.
The P5 therefore have a unique role in international peace and security, but they do not control every aspect of the United Nations.
For example, decisions concerning development, humanitarian assistance, health, education and climate involve many other UN bodies and Member States.
The current Security Council structure reflects the international political order that existed when the United Nations was founded in 1945.
The five countries were among the major Allied powers during World War II and were given permanent seats in the Security Council as part of the institutional design of the new international organization.
Today, reforming the Security Council is a major topic in international diplomacy. Some countries and regional groups have argued that the Council should better reflect the geopolitical and demographic realities of the 21st century.
No. Countries such as Germany, Japan, India, Brazil and many others can have major diplomatic, economic or regional influence within the UN system even though they do not have permanent Security Council seats.
The UN also operates through numerous specialized agencies, funds, programmes and other entities. Its work extends far beyond the Security Council.
Therefore, if you search for “5 main UN countries,” “UN permanent members,” “P5 countries,” or “five permanent members of the UN Security Council,” the answer is:
China, France, Russia, the United Kingdom and the United States.
