Since ascending to power in 2005, Iranian President Mahmoud Ahmadinejad has striven hard to maximize Iran's relations with the African continent.
In February 2009 and after a three-nation tour of Africa which took Ahmadinejad to Djibouti, Kenya and Comoros, the Iranian president termed expansion of Tehran's relations with African countries a "priority for Iran's foreign policy".
Iran is an observing member of the African Union and has shown an active presence in previous AU summit meetings.
