Samantha Power, head of the US Agency for International Development, went to Kenya and Somalia last week.
The US ambassador to the UN Linda Thomas-Greenfield will go to Ghana and Uganda next week.
“It’s like a new Cold War is playing out in Africa, where the rival sides are trying to gain influence,” said William Gumede, director of Democracy Works, a foundation promoting good governance.
Mr Lavrov, in his travels across the drought- and hunger-stricken continent, has sought to portray the West as the villain, blaming it for rising food prices, while the western leaders have accused the Kremlin of cynically using food as a weapon and waging an imperial-style war of conquest – words calculated to appeal to listeners in post-colonial Africa.
Under President Vladimir Putin, Russia has been working to win support in Africa for several years, reinvigorating friendships that date back half a century, when the Soviet Union backed many African movements fighting to end colonial rule.
“Now that campaign has gone into high gear,” Mr Gumede said.
Moscow’s influence in Africa was on display in March during the UN vote to condemn Russia’s invasion of Ukraine.
While 28 African nations voted in favour of the resolution, a significant minority of countries on the continent – 25 – either voted to abstain or did not vote at all.
Russia’s top diplomat this week visited Egypt, Congo, Uganda and Ethiopia, pledging friendship and accusing the US and European countries of driving up food prices by pursuing “reckless” environmental policies.
He also accused them of hoarding food during the Covid-19 pandemic.
“The situation in Ukraine did additionally negatively affect food markets, but not due to the Russian special operation, rather due to the absolutely inadequate reaction of the West, which announced sanctions,” Mr Lavrov said in Addis Ababa, Ethiopia’s capital.
Mr Lavrov was warmly received in Uganda by President Yoweri Museveni, who for years has been a US ally but has refused to criticise Russia over the invasion.
Mr Museveni even suggested at the outbreak of the war that Mr Putin’s actions might be understandable because Ukraine is in Russia’s sphere of influence.
Mr Lavrov voiced support for reform of the UN Security Council to give African countries permanent seats and greater influence.
Appearing with Mr Lavrov, the Ugandan leader spoke fondly of old ties with Russia, asking how he could spurn Moscow when he has good relations with countries that participated in slavery.
Mr Museveni, an opinion leader on the continent who has held power for three decades, is an obvious choice for Russia as someone to strengthen ties with, said Ugandan political analyst Asuman Bisiika.
“Uganda is the centre of gravity in East Africa,” Bisiika said.
Mr Museveni, 77, has been strictly wearing a mask in public since the Covid-19 outbreak.
But he did not have one on when greeting Mr Lavrov in front of photographers, apparently wanting to show warmth to the Russian.
Mr Museveni had a mask back on in his next public appearance a day later.
Russia is also courting African public opinion through its state television network RT, formerly known as Russia Today.
RT has announced that it will open a new bureau in Johannesburg.
RT was abruptly removed from Africa’s biggest pay-TV platform in Africa, Johannesburg-based Multichoice, in March after the European Union and Britain imposed sanctions against Russia.
It is not clear whether establishing the new bureau will enable RT to resume broadcasts to Africa through Multichoice, which claims nearly 22 million subscribers on the continent.
“For Russia, it is the battle to be heard in Africa. It is not important for the actual war effort but for their long-term political influence,” said Anton Harber, professor of journalism at the University of the Witwatersrand in South Africa.
“They see it as fertile ground to cultivate their influence and, of course, votes in the UN are important.”
On his tour of Africa, Mr Macron accused the Kremlin of using TV channels like RT to spread propaganda in support of the war.
And he accused the Kremlin of blackmailing the world by thwarting the export of grain from Ukraine.
“They are blackmailing because they are the ones who blocked cereals in Ukraine. They are the ones who regulate their cereals,” he said in Benin.
His itinerary also included Cameroon and Guinea-Bissau.
Mr Macron appealed to Africans to side against Russia.
“I’m telling you here in Africa, a continent that has suffered from colonial imperialism: Russia is one of the last colonial, imperial powers. She decides to invade a neighbouring country to defend her interests,” he said.
“That’s the reality.”
Ms Power was in East Africa to pledge aid to help the region’s fight against hunger amid a devastating multi-year drought.
She did not hold back in criticising Russia.
“By blockading Ukraine’s grain exports and restricting the trade of Russia’s own fertiliser, Putin’s actions have had the consequence of inflicting pain on the people of Kenya and on other countries throughout the world,” Ms Power said in Nairobi.
“He is hurting the people of Kenya in order to benefit his own situation.”
