The economically developed Guangdong province in southern China witnessed a stable growth in food exports in the first?ten 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 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, up 0.7 percent, increasing year-on-year for the fourth month in a row.

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?ten months of this year.
