The pledges were made on 31 January at a conference in London on reconstruction and reform in Afghanistan.
The United States promised to provide another $1.1 billion in support to the central Asian country, and Britain promised $805 million.
Representatives of some 70 countries and organizations attending the London meeting have also expressed support for helping implement the new "Afghanistan Compact."
This is a document which sets out a five-year plan for economic and social redevelopment in Afghanistan, including steps to improve security, impose the rule of law, and work towards stamping out illegal opium production and corruption.
