Seems like a power move to me. Painting a picture for the world of struggling U.S. institutions needing a Chinese billionaire's help to weather a crisis. I'm not even sure it's incorrect.
The Chinese are people like you and me. Yes their government needs a lot of work, but people are people and we need to remember that more.
I'm not saying it's evil or that we shouldn't accept it, I'm just observing the optics and the fact that there's no way the CCP didn't consider it from this perspective beforehand, regardless of any other motives.
