World Bank
Forty-five countries gave US$25.1 billion in "aid for the world's poorest countries", aid that goes to the World Bank International Development Association (IDA) which distributes the money to eighty poorer countries. While richer nations sometimes pay for their own aid projects, Robert B. Zoellick, the president of the World Bank, said when the gifts were announced on December 15, 2007, that World Bank money "is the core funding that the poorest developing countries rely on".
