In a rare display of confidence in the country's management of genetically modified food, China's top agriculture official said he eats GM food.

"I now also eat food processed from GM raw materials, specifically soybean oil, because it's mainly made from imported soybeans, most of which are genetically modified," Minister of Agriculture Han Changfu said while answering a China Daily question on the sidelines of the annual legislative session on Thursday.

The video clip and news report of the minister's remark went viral on the Internet on Thursday afternoon, a signal that the safety of GM food is a big public concern.

Soybean imports, Han said, have undergone a chain of stringent procedures and had passed safety tests in both exporting countries and in China.

Han's ministry previously said import certificates for GM crops in China had been awarded only for soybeans, corn, rapeseed, cotton and beets. These imports are only allowed to be used as raw materials for domestic processing.

The minister reiterated China's position on transgenic technology that the country must strive to keep up with the world's advanced level and that it must possess its own intellectual property rights.

China has already raked in profits from its GM research. GM cotton, for instance, has not only increased yield and income for farmers, but also drastically cut the use of pesticides, said the minister.

Transgenic cotton accounts for 95 percent of the Chinese market, he added.

"We've actually exercised extreme caution on GM plants," the minister said.
