The chairman of the African Union commission, Moussa Faki Mahamat, held a phone conversation with Russia's Foreign Minister Sergei Lavrov on Tuesday.
Mr Faki posted on Twitter that he "stressed the need to respect international law and urged for dialogue and a peaceful resolution" to the war in Ukraine.
Last week, Ukrainian President Volodymyr Zelensky reached out to his Senegalese counterpart and African Union chairman, Macky Sall, requesting to address the AU.
President Macky Sall said he “noted” Mr Zelensky’s request. He also called for dialogue to end the war.
The conflict has led to sharp increases in fuel and wheat prices in Africa and threatens to further worsen economies devastated by the Covid-19 pandemic.
