SHANGHAI, China - "For the first time in six years, Chinese grain harvests are falling short of demand and reviving the question: Will China be forced to rely on imports to feed itself?
Since late summer, wheat prices in the northeast have shot up by 32 percent; corn prices have doubled and rice prices are up by as much as 13 percent, according to official reports. Prices of edible oil, vegetables, meat and other food products have also jumped. Grain harvests this year are estimated to have fallen for the fifth year in a row -- hit by a double whammy of bad weather and cutbacks in acreage.
EDIT
In recent years, the country has capped net grain imports at about 5 percent of total consumption. Given its history of famine, China has made self-sufficiency in grain a strategic priority, viewing a stable food supply as key to national security and stability. But because of rising demand, environmental limits and the opening up of markets, China may now be forced to loosen its policy of virtual self-reliance.
EDIT
Grain output peaked at 392 million tons in 1998 and has fallen ever since, according to the U.S. Department of Agriculture. It terms Chinese demand for wheat a "key source of uncertainty" in world markets."
