A delegation of six African leaders set to hold talks with Kyiv and Moscow aim to “initiate a peace process,” but also broach the thorny issue of how a heavily-sanctioned Russia can be paid for the fertiliser exports Africa desperately needs, a key mediator who helped broker the talks said.

Jean-Yves Ollivier, an international negotiator who has been working for six months to put the talks together, said the African leaders would also discuss the related issue of easing the passage of more grain shipments out of Ukraine amid the war and the possibility of more prisoner swaps when they travel to both countries on what they’ve characterised as a peace mission.

The talks will likely be next month, Ollivier said.

He arrived in Moscow on Sunday and will also go to Kyiv for meetings with high-level officials to work out “logistics” for the upcoming talks. For one, the six African presidents would likely have to travel to Kyiv by night train from Poland amid the fighting, he said.

Russian President Vladimir Putin and Ukrainian President Volodymyr Zelenskyy have both agreed to separately host the delegation of presidents from South Africa, Senegal, Egypt, Republic of Congo, Uganda and Zambia.

The talks also have the approval of the United States, the European Union, the United Nations, the African Union and China, Ollivier said in a video call with the AP on Friday.

Neither side in the war appears ready to stop fighting, though.

The talks were announced last week by President Cyril Ramaphosa of South Africa just as Russia launched an intense air attack on Kyiv. On Sunday, Russia claimed to have taken the key eastern Ukrainian city of Bakhmut after fierce fighting, a claim denied by Ukraine.

“We are not dreamers,” Ollivier said on the chances the African leaders will achieve an immediate breakthrough with regard to stopping the 15-month conflict. “Unless something happens, I don’t think we are going to finish our first mission with a ceasefire.”

The aim was to make a start, said Ollivier, a 78-year-old Frenchman who brought opposing sides together in high-stakes negotiations in the late 1980s that helped end apartheid in South Africa.

“It starts with signs. It starts with dialogue. And this is what we are going to try to do,” Ollivier said. “No guarantee that we are going to succeed but, for the time being, Russia and Ukraine have accepted … a delegation coming specifically to their countries to talk about peace.”

A key starting point for Africa is grain and fertilisers.

The war has severely restricted the export of grain from Ukraine and fertilisers from Russia, exacerbating global food insecurity and hunger. Africa has been one of the hardest-hit continents. Last week, Russia agreed to a two-month extension of a deal brokered by Turkey and the UN that allows Ukraine to ship grain through the Black Sea and out to the world, and the six African presidents would like to see that extended further.

But they also need to broach ways of making it easier for African nations to receive shipments and pay Russia for fertilisers, Ollivier said. Russian fertiliser is not under international sanctions but the US and some Western nations have targeted Russian cargo ships for sanctions. Russia’s access to the SWIFT global financial transaction system also has been restricted by the sanctions, leaving African nations struggling to order and pay for critical fertilisers.
