He is trying to "reorient" his country, which is experiencing economic problems, the government said.
Accompanied by his economy minister, Milei will meet representatives from OpenAI, Apple and Google this week, as well as Meta CEO Mark Zuckerberg, presidential spokesman Manuel Adorni told reporters.
The ultra-liberal president will meet with "the owners of four of the 10 largest companies by market capitalization in the world in this attempt to position Argentina globally," Adorni added.
It is Milei's seventh trip overall since December and comes in the week the Senate will debate his package of budget-cutting and liberalizing economic reforms.
Milei's last trip abroad - to Spain - sparked a major diplomatic row last week after he called the prime minister's wife "corrupt" at a meeting of far-right leaders in Madrid.
Since taking office, Milei has slashed public spending, cut the cabinet in half, eliminated tens of thousands of civil service jobs, halted new construction contracts, and removed fuel and transport subsidies.
Although inflation is slowing, it is still close to 290% year-on-year and industrial production is falling sharply. / BGNES
