Japan's SoftBank pledged to spend 75 billion euros ($87.5 billion) on artificial intelligence infrastructure in France, its founder Masayoshi Son said in an interview published Saturday.

"This will be the largest investment in Europe in infrastructure related to artificial intelligence: 75 billion euros in total," Son told La Tribune Dimanche weekly ahead of a French investment conference hosted by President Emmanuel Macron.

He said it included 45 billion euros to be spent by 2031 on data centers in the Hauts-de-France region of northern France.

French electric giant Schneider will be a partner in the huge project, its chief executive, Olivier Blum, told Agence France-Presse (AFP).

"This is a significant partnership, a major project, the largest ever undertaken in France" in the sector, said Blum.
