Leaders of the BRICS group of developing nations have invited Saudi Arabia, Iran, Ethiopia, Egypt, Argentina and the United Arab Emirates to join, in a move aimed at growing the clout of a bloc that has pledged to champion the "Global South".
Expansion could also pave the way for dozens of interested countries to seek admission to BRICS – currently Brazil, Russia, India, China and South Africa – at a time when geopolitical polarisation is spurring efforts by Beijing and Moscow to forge it into a viable counterweight to the West.
