The Cotonou agreement recognises the specific challenges faced by less developed countries, land-locked countries, and islands in their economic development. Therefore, those countries are granted a more favourable treatment than other ACP member countries. The text of the Cotonou agreement has been updated in 2005 and 2010, but the lists have not, despite the fact that the actual list of LDCs as defined by the United Nations has changed: Cape Verde has graduated from LDC status in December 2007, while Senegal has acquired the status in 2001 and Timor-Leste in 2003.
