South African President Cyril Ramaphosa says the Group of 20 bloc has sufficient “shock absorbers” to function effectively if a Donald Trump administration promotes an America First policy at the expense of international cooperation.

South Africa's G20 presidency next year will focus on mobilising finance for nations stricken by climate-induced disasters and extending debt relief for developing countries, President Cyril Ramaphosa said on Tuesday.

South Africa says it will use its presidency of the G20 – the first by an African nation – to put the priorities of the African continent onto the agenda of the powerful global economic forum.
