China's property crisis may take up to a decade to resolve, economist Hao Hong told CNBC. Hong's WeChat and Weibo social media accounts were suspended last year after a series of bearish posts on China's economy. "Fixing the property sector may be a multi-year or even a decade's work in front of us. The property sector, along with related industries, contributes as much as 30% to the country's GDP. Still, there may be an upside ahead for China's economy once the property market's problems are resolved, Hong told CNBC.
