A Chinese investor walks past an investment map showing suitable property markets for wealthy Chinese to invest in at the International Property Expo in Beijing on April 11, 2014.  Wealthy Chinese will pour AUD$44 billion (US$39.4 billion) into Australian real estate over the next seven years, potentially pushing prices in one of the world's most expensive housing markets even higher. Chinese property investors have been on a international spending spree since the global financial crisis hit most of the world's economies.
