Doha, being dubbed the "Development Round" of negotiations, implied benefits to the poorest countries. However, the non-deliverance of these "benefits" is another reason for its failure (at least in some cases):

Yet, after a decade of damaging results, many people in the 149 WTO signatory nations have made clear their opposition to more of the same. This was before the World Bank dramatically revised downward its projections of Doha Round gains and revealed that a long list of poor countries would be net losers under the likely outcome. While U.S. and European editorials declared the Doha Round collapse as disaster for the poor, social movements and NGOs representing the populations of poor countries cheered.
