China's grain yield this year will "definitely" hit a record high despite shortages in the world, a senior agricultural official said.

It will be the fifth consecutive year of high grain yield. The output this year is likely to break the record of 512 million tons established in 1998. Last year, the yield was 501.5 million tons.

"Our wheat yield also achieved a new high this summer," the official from the Ministry of Agriculture told China Daily yesterday on condition of anonymity.
