  The main administrative capital of the African Union is in Addis Ababa, Ethiopia, where the African Union Commission is headquartered. A new headquarters complex, the AU Conference Center and Office Complex (AUCC), was inaugurated on 28 January 2012, during the 18th AU summit. The complex was built by China State Construction Engineering Corporation as a gift from the Chinese government, and accommodates, among other facilities, a 2,500-seat plenary hall and a 20-story office tower. The tower is 99.9 meters high to signify the date 9 September 1999, when the Organisation of African Unity voted to become the African Union. The building cost US$200 million to construct.
