And we are very impressed that you have taken this leadership position and the time to be with us here.“We want to support and build up countries who have leaders like those here before you to take their rightful place of leadership by regionally and globally.”President Barrack Obama is expected to deliver the keynote address at the food security symposium later today with Presidents Mills, Jekaya Kikwete of Tanzania and Prime Minister Zenawi of Ethiopia being discussants.Policy think tank IMANI Ghana is however casting doubts the participation of Africa will guarantee improved food security on the continent.Its Communications Director, Selorm Brantie says African countries do not need such meetings with world powers to solve their agricultural problems.Meanwhile, international NGO Oxfam is asking the African leaders to hold the G8 countries accountable for unfulfilled promises made in previous summits.
