What exactly does this "investing" mean here? Do they essentially donate money to Trump? Do they buy American factories/companies? Do they build new factories? Do they just announce and investment and then nothing happens for a long time?

In other words, who makes the profit here? Did they rip off the Trump without him noticing or did they get ripped off and can't do anything about it? Is "investing" another way of saying "ASiAnS BuY MuRIcaN ComPnAIEs!!!1!" that is more popular with the maga crowd?

All the reports I've seen about this just regurgitate the government speech and give no useful details what's really going on here.
