The theme for the 16th African Union Summit in Addis Ababa is 'Towards Greater Unity and Integration through Shared Values'. Arguably, the success story of South-South cooperation around shared values is the African Peer Review Mechanism, says the South African Institute of International Affairs. It is the continent’s home-grown governance tracking system and will be re-examined when African leaders meet on the summit margins. Key agenda items for the APRM forum include Liberia’s accession as the APRM’s 30th member, the much-anticipated peer review of Ethiopia, and progress reports on the National Programmes of Action (NPoAs) from South Africa, Lesotho and Nigeria.
