China's real estate market to remain cool next year

China's tightening policy aimed at cooling exorbitantly growing property market has led to slowdown of the real estate sector's expansion.  Experts predict the next year will be even tougher to the industry. Expected amount of sales contracts to be signed by the end of 2011 equals 9.5 million sq m for new houses that is 23% lower than a year before and is the smallest amount in the last 10 years.
