The international community rallied to Haiti's defense during the 1991-94 period of de facto military rule. Thirty-one countries participated in the U.S.-led multinational force (MNF) which, acting under UN auspices, intervened in September 1994 to help restore the legitimate government and create a secure and stable environment in Haiti. At its peak, the MNF included roughly 21,000 troops, mostly Americans, and more than 1,000 international police monitors. Within 6 months, the troop level was gradually reduced as the MNF transitioned to a 6,000-strong peacekeeping force, the UN Mission in Haiti (UNMIH). UNMIH was charged with maintaining the secure environment which the MNF had helped establish as well as nurturing Haiti's new police force through the presence of 900 police advisers. A total of 38 countries participated in UNMIH.

To spur Haiti's social and economic recovery from decades of misrule before that, international donors pledged in 1994 to provide more than $2 billion over five years in total assistance. Most bilateral assistance is now channeled through non-governmental organizations. Major bilateral donors are led by the United States, with the largest program, and include Canada, the EU, France, Germany, Japan, and Taiwan. Cuba provides highly visible, low-cost medical and technical experts. Multilateral aid is provided by the Inter-American Development Bank (IDB), International Monetary Fund, World Bank, and the UN and its agencies. All aid is coordinated informally by the World Bank.

In July 2004, $1.085 billion was pledged through 2006 at the World Bank Donorsí Conference. Donors include the U.S., Canada, the EU, France, Sweden, Spain, Germany, Japan, Switzerland, Greece, Norway, Mexico, and Ireland. The IDB and the World Bank pledged multilateral aid. As of March 2006, $965 million had been disbursed, mainly to address humanitarian needs.
