The United Nations is expressing concern over the economic impact of the Russia-Ukraine conflict, particularly on developing countries due to increased prices in food, fuel, and fertilizer caused by the disruption in the global supply of sunflower oil and wheat. Secretary-General Antonio Guterres has called for an immediate cease-fire and peace negotiations, as the war is exacerbating the struggles of poor nations, some of which rely heavily on Ukrainian grain. The U.N. is also seeking more funding for humanitarian aid in Ukraine and is shifting its resolution on the humanitarian crisis from the Security Council to the General Assembly, in anticipation of potential vetoes and to gather broader support for its demands.
