China will increase the size of its granaries as its grain output rises and also take steps to reduce losses from substandard grain storage facilities, as part of the ongoing efforts to bolster food security.

During a trip to Zhuzhou, Hunan province, on Friday, Premier Li Keqiang urged China Grain Reserves Corp, the country's largest and most wide-ranging grain storage and transportation company, to work on more options to improve its rice rotation mechanism and reduce storage of expired rice.

Li said grain reserve companies should make more room for new grain by selling old stocks and conduct special inspections to ensure that all the national granaries are efficiently used for storing grain.
