I wouldn't even say it's speculative condo buying - it's more like treating the condo as a piggy bank. It's considered a safer investment because it can be purchased through a shell company (LLC), hiding the true identity of the buyer, and unlike the funds in a bank account, can't easily be seized.

There was a well known phenomenon: http://www.nytimes.com/2015/11/29/business/international/chi...

"In London, Chinese investors are purchasing high-end apartments in wealthy neighborhoods and big skyscrapers in the financial district. In Canada, they are paying $1 million for modest Vancouver bungalows. In Australia, a Chinese sovereign wealth fund bought nine office towers, one of the biggest real estate transactions in that nation’s history."
