BEIJING — China's consumer inflation unexpectedly eased in September, while producer price deflation deepened, heightening pressure on Beijing to roll out more stimulus measures quickly to revive flagging demand and shaky economic activity.

Finance Minister Lan Foan told a news conference on Saturday there will be more 'counter-cyclical measures' this year, but officials did not provide details on the size or timing of fiscal stimulus being prepared, which investors hope will ease deflationary pressures in the world's second-largest economy.
