Angola has acted as a mediator in the conflict in eastern Congo, which escalated in late January when the Rwanda-backed rebels advanced and took control of the strategic eastern Congo city of Goma. M23 seized Bukavu, eastern Congo's second biggest city, last month.

Angolan President João Lourenço, currently chair of the African Union, has called for an immediate ceasefire in the ongoing conflict in the eastern Democratic Republic of the Congo (DRC). President Lourenço on Saturday called for a ceasefire ahead of peace talks he will be hosting.

Rwanda-backed M23 rebels on Monday pulled out of peace talks with the Democratic Republic of Congo's government less than 24 hours before the warring parties in eastern Congo's worst conflict in decades were due to convene in Angola.
