SHANGHAI, March 10 (Reuters) - China shares closed weaker on Tuesday as banking stocks stepped back after Monday's surge, as data showed increased factory sector deflation hurting the pricing power of Chinese firms.
Tighter liquidity also contributed to market weakness, analysts said, as investors started subscribing to new shares issued by Lens Technology Co Ltd, the first in a series of initial public offerings this week.
