Mr. Musk has declared lithium — the silvery-white element that is the main component in Tesla’s car batteries — “the new oil.” Tesla has long bought lithium from Argentina, which has the world’s second-largest reserves. Now Mr. Milei is pushing for major benefits for international lithium miners, which would likely give Tesla a more stable — and potentially cheaper — flow of one of its most critical resources.
Mr. Milei is part of a pattern by Mr. Musk of fostering relationships with a constellation of right-wing heads of state, with clear beneficiaries: his companies and himself.
Mr. Musk, 52, has repeatedly used one piece of his business empire — X, formerly known as Twitter — to vocally support politicians like Mr. Milei, Jair Bolsonaro of Brazil and Narendra Modi of India. On the platform, Mr. Musk has backed their views on gender, feted their opposition to socialism and aggressively confronted their enemies. Mr. Musk even personally intervened in X’s content policies in ways that appeared to aid Mr. Bolsonaro, two former X employees said.
Mr. Musk, in turn, has pushed for and won corporate advantages for his most lucrative businesses, Tesla and SpaceX, according to an examination by The New York Times. In India, he secured lower import tariffs for Tesla’s vehicles. In Brazil, he opened a major new market for Starlink, SpaceX’s satellite internet service. In Argentina, he solidified access to the mineral most crucial to Tesla’s batteries.
Mr. Musk’s endorsement has given many nationalist and right-wing heads of state more international cachet, which they have eagerly promoted as a validation of their policies and popularity. Last month, as India began holding an election, Mr. Modi prepared to host Mr. Musk in New Delhi, calling the billionaire’s visit a testament to his leadership.
