Foreign ministers and senior diplomats from leading rich and developing countries focused on global conflicts, including the Russia-Ukraine war, on the last day of their meeting in South Africa.

South African President Cyril Ramaphosa on Thursday opened the two-day G20 Foreign Ministers' Meeting in Johannesburg, the largest city and economic hub of South Africa, where he called for multilateralism and the application of international law in resolving world crises.

South Africa's G20 presidency was meant to be an opportunity to get rich, powerful nations to pay attention to poorer countries' concerns such as burgeoning inequality, crippling sovereign debt and a lack of progress in the fight against climate change.
