The major objective of **price stability in the international oil market** is primarily associated with the **Organization of the Petroleum Exporting Countries (OPEC)**.
OPEC is an organization consisting of oil-producing countries, and its primary aim is to **coordinate and unify the petroleum policies** of its member countries. This coordination ensures that the oil market is stable, prices are reasonable, and there is a consistent supply of oil to consumers.
OPEC achieves this by determining the **production levels** of its member countries. By doing so, it can either increase or decrease oil production to influence oil prices. For instance, if there is too much oil in the market, leading to falling prices, OPEC may choose to lower production to stabilize or increase prices.
This function is not a direct objective of organizations such as the **United Nations (UN)**, which focuses on maintaining international peace and security, or the **World Trade Organization (WTO)**, which addresses trade rules between countries. Similarly, the **African Union (AU)** concentrates on regional integration and development within Africa.
