Argentinian President-elect Javier Milei has done a complete 180 on Buenos Aires joining BRICS, saying the South American nation won't be joining the five-nation group.

Diana Mondino, senior economic adviser to Milei, confirmed this development to Sputnik Brazil on Nov. 20, a day after Milei won the country's second presidential runoff. She told the outlet that Argentina was not planning to become a BRICS member come Jan. 1, 2024. The nation's prior request to join the group was approved in August – alongside those from Egypt, Ethiopia, Iran, Saudi Arabia and the United Arab Emirates.

"I don't know why there is so much interest around BRICS," said Mondino, who is Milei's candidate for foreign minister in his cabinet. She added that it remained uncertain as to how joining the group would benefit Buenos Aires. Nevertheless, Mondino remarked that the government will "analyze" if joining the BRICS would reap rewards for the country.
