There are three main types of aid:
1) Political (bilateral) aid which is given directly from one government to another, often with conditions attached for the recipient country to buy goods from the donor country.
2) Multilateral aid which is given to international agencies like the UN to distribute as they see fit, often targeting large projects and not always meeting local needs.
3) Charitable aid from NGOs which works closely with local communities to target aid directly to those most in need, making it more effective.
