(Reuters) -Elon Musk, the CEO of Tesla and SpaceX, said in a post on X on Tuesday that his companies were looking for ways to invest in Argentina and support the South American nation.

Argentina is the world's fourth-largest producer of lithium, a critical component of electric vehicle batteries.

Musk has previously showed admiration for Argentine President Javier Milei's libertarian politics and his full-throated embrace of private enterprise. The billionaire hosted Milei at a Tesla factory in Austin, Texas, in April.

"My companies are actively looking for ways to invest in and support Argentina," said Musk, whose companies also include brain-chip startup Neuralink and artificial intelligence firm xAI.
