Marley currently rests in his homeland of Jamaica after he died of cancer in 1981. He will be moved to Shashemene in Ethiopia next month in celebration of his 60th birthday.
Speaking to the BBC, Rita said, "We are working on bringing his remains to Ethiopia. It is part of Bob's own mission."
Ethiopia has been chosen because it was the birthplace of Rastafarian leader Haile Selassie. A film festival and seminars will also take place in commemoration of the Buffalo Soldier singer.
