The African Union permanent Ambassador to the United States, Dr Arikana Chihombori-Quao, was served her sack letter earlier this week because of her comment on neo-colonialism in Africa mostly by the French government on Francophone African countries.
The letter was signed by the AU chairperson Musa Faki Mahamat which was dated October 7, and it will take effect from November 1, no reasonable reasons has been issued for her termination as the AU ambassador, but her recent address criticising French Neo colonialism may as well play a significant role.

Her sacking has shown to our face that the economic and political independence of African countries have not been achieved and the celebration of independence is just of a show of confusion and shame by African countries, it is disheartening to hear that even our continental organisation is still a slave to western imperialism and neo-colonialism.
