Foreign aid is a country helping another country by giving money or things or sending people. That is especially needed when a disaster happens in a poor country. The help is sometimes comes from a country's government, but the country's ordinary people sometimes give money. Foreign aid may help by giving food and clean water to people who need them. A charity usually donates to the developing countries. Some aid is for economic development.
The poorer countries are called LEDCs (Less Economically Developed Countries). The richer countries are called MEDCs (More Economically Developed Countries).
The United Nations and the Organization for Economic Co-operation and Development also work for such aid for poorer countries.
