The United Nations Office to the African Union (UNOAU) was established by UN General Assembly Resolution 64/288 in 2010. 

The integrated Office has three core aims:

• Enhance the partnership between the United Nations and the African Union in the area of peace and security;
• Provide coordinated and consistent United Nations advice to the African Union on long-term capacity-building and short-term operational support matters;
• Streamline the United Nations presence in Addis Ababa to make it cost-effective and efficient in delivering UN assistance to the AU.
