Billionaire Elon Musk told Italy League leader Matteo Salvini on Saturday that he hoped in the future the U.S. and Europe could create “a very close, stronger partnership” and reach a “zero-tariff zone.”

Musk spoke to Salvini in a video conference during the League’s congress in Florence. Salvini is the leader of the far-right, anti-migrant League party and vice premier of the Italian conservative government led by Premier Giorgia Meloni.

He said that, ideally, there will be a “zero-tariff zone in the future with a free trade zone between Europe and North America.”

Musk, an adviser to President Donald Trump who owns Tesla, SpaceX and the social media platform X, has played a key role in government downsizing as the head of the newly created Department of Government Efficiency.
