BUENOS AIRES—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 right-wing President Javier Milei.
In a letter addressed to the leaders of Brazil, Russia, India, China, and South Africa—all members of the alliance—Mr. 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.
Argentina was among six countries invited in August to join the bloc made up of Brazil, Russia, India, China, and South Africa to make an 11-nation bloc. Argentina was set to join Jan. 1, 2024.
The move comes as Argentina has been left reeling by deepening economic crisis.
Mr. Milei’s predecessor, former President Alberto Fernandez, endorsed joining the alliance as an opportunity to reach new markets. The BRICS currently account for about 40 percent of the world’s population and more than a quarter of the world’s GDP.
But economic turmoil left many in Argentina eager for change, ushering chainsaw-wielding political outsider Mr. Milei into the presidency.
Mr. Milei, who defines himself as an “anarcho-capitalist”—a current within liberalism that aspires to eliminate the state—has implemented a series of measures to deregulate the economy, which in recent decades has been marked by strong state interventionism.
In foreign policy, he has proclaimed full alignment with the “free nations of the West,” especially the United States and Israel.
Throughout the campaign for the presidency, Mr. Milei also disparaged countries ruled “by communism” and announced that he would not maintain diplomatic relations with them despite growing Chinese investment in South America.
However, in the letter addressed to his counterpart Luiz Inácio Lula Da Silva in neighboring Brazil and the rest of the leaders of full BRICS members—Xi Jinping of China, Narenda Mondi of India, Vladimir Putin of Russia, and Matamela Ramaphosa of South Africa—Mr. Milei proposed to “intensify bilateral ties” and increase “trade and investment flows.”
Mr. Milei also expressed his readiness to hold meetings with each of the five leaders.
