Sina.com's (SINA) Real Estate channel has started services covering Chongqing, China's largest municipal area.

After other heavyweights like Soufun.com and Sohu.com (SOHU), Sina is the third major portal to launch a comprehensive property information site for the area.

The new channel will be responsible for collecting, classifying and releasing real estate news, newly developed buildings and housing advertisements.

While areas like Shanghai and Beijing are thought to be in a property bubble, areas in China's West, like Chongqing, are only now beginning to reap the benefits of China's rapid growth.
