China is uniquely suited to generate buyers that will bid up Vancouver real estate. PRC business owners have, over the last 20 or so year, been very successful in expanding their businesses outside of the PRC and thus have large amounts of foreign sourced earnings.  The PRC's monetary policies actively dissuade repatriation of foreign earnings because they are difficult to get out again once repatriated.  As such those earnings are looking for non-PRC assets to invest in.  Vancouver real estate, with a >20% annual return for many years, is a very attractive investment vehicle.  Further, it is an investment people can live in, or let their relatives live in, which gives it additional value as an asset class.  Finally, Vancouver is a welcoming city to live in for people whose primary language is Mandarin or Cantonese.  Put all that together and you have a substantial amount of interest in Vancouver real estate from people in the PRC.  There is no scapegoating there.  It's just true.
