The decision-making rules of the International Monetary Fund (IMF) are very distinctive, and the weighted voting system is implemented.

The voting right consists of two parts, each member country has 250 basic voting rights and weighted voting rights according to the share paid by each country. Because the basic votes are the same in all countries, the weighted voting right plays a decisive role in actual decision-making.

The weighted voting right is directly proportional to the share paid by each country, and the share is determined according to a country's gross national income, the degree of economic development, the degree of international trade before the war and other factors.
