Regional bloc ECOWAS was the first to lift sanctions on Bamako after the West African country’s government appointed a civilian Prime Minister.
In a post on Twitter, the AU’s peace and security council said it was satisficed by recent political developments in Mali.
ECOWAS’s sanctions included border closures, a trade and monetary embargo.
Mali’s transitional government headed by former defence minister Bah Ndaw has been given 18 months to organise elections and hand over power.
Faced with a troubled economy, a militant insurgency and a pandemic, the sanctions had made it hard for Bamako to import critical supplies and stifled its revenue sources.
