President-elect Donald Trump said Tuesday that Japanese tech conglomerate SoftBank will invest $50 billion in American start-up companies.

SoftBank Group Corp founder and chief executive officer Masayoshi Son visited Trump Tower Tuesday. Trump made the announcement about the investment after their meeting on both Twitter and in front of the press in his tower’s lobby.

“Ladies and gentlemen, this is Masa from Japan. He’s just agreed to invest $50 billion in the United States and 50,000 jobs. He’s one of the great men of industry, so I just want to thank you very much,” Trump said. The SoftBank CEO then told the press, “I just came to celebrate his new job. I said, ‘This is great, the U.S. will become great again.'”

He added that the $50 billion investment will go towards start-ups. Trump tweeted out about the investment, “Masa said he would never do this had we (Trump) not won the election!”
