China's golden era of red-hot expansion may be over, but the real estate sector still stands to see sustainable double-digit growth, according to the billionaire behind shopping mall developer Dalian Wanda Group.

"While we are unlikely to see super-fast yearly growth of 30-40 percent as we've seen in the past, I expect a sustainable and steady growth rate of 10 percent that's likely to persist for the next 10 years," Wang Jianlin, chairman of the Beijing-based property and leisure conglomerate, told CNBC's "Managing Asia."
