Foreign aid can take various forms, including bilateral aid between governments, multilateral aid from organizations like the World Bank, and tied aid which must be spent in the donor country. The main purposes of foreign aid are economic development and welfare of recipient countries. While foreign aid aims to help developing nations, critics argue it does not always promote faster growth and can increase inflation or allow interference by donor nations. Supporters counter that foreign aid improves human welfare, builds international relationships, and promotes global stability.
