The United Nations on Monday begged world trade ministers meeting at the WTO not to impose export restrictions on food for humanitarian purposes, amid a food security crisis. The UN’s human rights chief Michelle Bachelet and its trade and development head Rebeca Grynspan said Russia’s war in Ukraine was increasing the risk of hunger and famine for tens of millions of people who are already food insecure or approaching food insecurity. Countries meeting at the World Trade Organization’s ministerial conference in Geneva this week are trying to reach a consensus position on food security.
