The economically developed Guangdong province in southern China witnessed a stable growth in food exports in the first 10 months, thanks partly to the nation's tax rebate policy for exports, according to local customs.

Between January and October, Guangdong exported 3.59 billion U.S. dollars worth of food products, up 2.7 percent over the same period of last year.

In October, the province's food exports were valued at 400 million U.S. dollars, up 0.7 percent, increasing year-on-year for the fourth month in a row.

Local customs said the tax rebate policy that took effect as of June 1 had somehow offset cost rise, in part resulting from appreciation of the Chinese currency, for exporters.

Foods products made up around 50 percent of export products covered by the tax rebate policy.

However, the local customs said fears about food security and trade barriers still hampered China's food exports.

As a major foreign trade base, Guangdong accounted for 27.5 percent of China's total import and export volume in the first 10 months of this year.
