Generally when foreigners start buying up US assets, there's a minor panic at the time, but they tend to overpay for prestige assets, and usually the buying binge fades and they lose money on their purchases.
Of course, I'm thinking the Japanese and Saudis, which both became wealthy societies in a short span of time. And both were allies. While China is still a developing country, though with some stunning wealth and great inequality. And more strategic purchases in line with gov't directives.
Lotta Russians were/are buying up NYC real estate to launder their money and stash it abroad. US is a large economy. Stuff to monitor but not get too concerned about.
