The poorest countries need support from the international community if they are to achieve the Millennium Development Goals, says Gyan Chandra Acharya, the United Nations official for least developed countries. One-half of people in the 49 poorest countries still live below the World Bank's $1.25-a-day threshold. "We must make sure that the unfinished agenda is taken care of. ... There is no way they can do it themselves," Acharya said.
