This is a very complex question. International economic institutions help less developed countries through various international bodies such as World Bank, mostly providing developement aid. Through UNDP, that helps in eliminating poverty through development. The IMF helps in stabilizing international exchange rates and providing developement infrastructure.

The WTO (World Trade Organization) is a International Economic Institution that helps developing countries have opportunities to increase their trade flows and participate in the world marketplace better. The World Bank provides low-interest loans and grants to developing countries to help investments in health, education, infrastructure among other areas of the developing countries. They also provide these countries with assistance, advice and researches on their investments. The International Monetary Fund (IMF) is part of a vast international effort to reduce poverty and improve health in the world's poorest countries.
