Irvine, CA has this occurring. 2014 numbers reported that 80% of single family homes in the area were bought by Chinese families (random first google hit article on it: http://www.zerohedge.com/news/2015-09-30/80-all-new-home-buy...). A lot of the Irvine Company apartments top-level units are effectively birthing centers on the down low, but nobody really seems to take much issue with it.

There is also a significant rich foreign Saudi presence in Irvine and that's definitely more of a culture clash due to the misogynistic nature of mother/son relationships. Super spoiled kids, "slavery" scandals, etc but the money "donated" to Irvine company for things like renovating the spectrum mall is massive. Considering Irvine company owns ~90% of Irvine, I think this foreign interest can't be overlooked in lieu of the more public Chinese impact.
