BEIJING, Jan 20 (Reuters) - China's cooling housing sector has shown some positive signs in activity on the back of policy support, the Chinese statistics bureau said on Tuesday.

Plagued by falling prices and a large inventory of unsold homes, China's property market suffered a slump last year to become one of the main drags on the Chinese economy.

Data released on Tuesday showed China's property investment growth cooled to 10.5 per cent in 2014 from a year earlier, as revenues from housing fell 6.3 per cent.
