You might try local Realtors (especially those who specialize as buyer agents) that advertise in Chinese (or that they speak Mandarin or Cantonese) to see if any recent transactions fit the bill.
Also, sales are open record - you might look at buyers with Chinese surnames that lack Americanized first names.

We've been here before: back in the 80s, Japan was buying up most of the real, tangible assets in the U.S.
