His economic measures stalling at home, Argentina's self-styled anarcho-capitalist president, Javier Milei, has taken to touring the world to hold often-raucous appearances before fans and investors, from Israel to Spain to the U.S.

"A wonderful meeting about AI and the enormous possibilities offered by a libertarian Argentina," Milei wrote Tuesday on X, posting a picture after meeting with OpenAI's chief executive, Sam Altman, in San Francisco.

In his seventh foreign trip since taking office in December, the libertarian hit California to meet Wednesday with Google's Sundar Pichai before moving on to see Apple's Tim Cook. On Thursday's schedule is Meta Platforms' Mark Zuckerberg, as Milei advocates for investment in Argentina and touts his efforts to radically overhaul the nation's heavily protectionist and bruised economy.
