The U.N. secretary-general called Friday for nations to build a world that is more fair for developing countries, as he kicked off a summit in Cuba of the G77 group of emerging economies plus China.
Secretary-General Antonio Guterres said that while many of the countries of the G77 have helped lift millions of people from poverty, they still face a lot of crises, including hunger, inflation, climate disasters and debt, and they haven't gotten enough help.
