Foreign aid is when one country helps another country. The country may give money or things; it may also send people. This is especially needed when a disaster happens in a poor country. Sometimes this help comes from a country's government and sometimes the ordinary people give money. Some foreign aid helps by giving food and clean water to people who need them. Most of the time it is a charity which donates to the poor countries. The poor countries are called LEDC's (Less Economically Developed Countries).
United Nations and Organization for Economic Co-operation and Development also work for such aid for poor countries.
