The ongoing conflict in Ukraine has aggravated the food, energy and finance crisis in Africa, United Nations Secretary-General Antonio Guterres said on Sunday. During a joint press conference with Senegalese President Macky Sall, Guterres said he had set up a Global Response Group to help mobilize United Nations agencies, development banks and other international organizations to mitigate the effects of the crisis, particularly in Africa. Guterres called for lifting all unnecessary export restrictions to establish a steady flow of food and energy' in open markets, and to control food prices. 'There will be no real solution to the problems of food security without reintegrating the agricultural production of Ukraine, as well as the food and fertilizer production of Russia and Belarus in world markets,' he said. Regarding the energy crisis, the UN chief urged all countries to release strategic stocks and additional reserves for countries in need by accelerating the promotion of renewable energies.
