BUENOS AIRES (AP) — Argentina formally announced Friday that it won’t join the BRICS bloc of developing economies, the latest in a dramatic shift in foreign and economic policy by Argentina’s new far-right populist President Javier Milei.

In a letter addressed to the leaders of Brazil, Russia, India, China and South Africa — all members of the alliance — Milei said the moment was not “opportune” for Argentina to join as a full member. The letter was dated a week ago, Dec. 22, but released by the Argentine government on Friday, the last working day of 2023.
