Haiti received more than US$4 billion in aid from 1990 to 2003, including US$1.5 billion from the United States. The largest donor is the US, followed by Canada and the European Union. In January 2010, following the earthquake, US President Barack Obama promised US$1.15 billion in assistance. European Union nations pledged more than €400 million (US$616 million). Neighboring Dominican Republic has also provided extensive humanitarian aid to Haiti, including the funding and construction of a public university, human capital, free healthcare services in the border region, and logistical support after the 2010 earthquake.
