All certified genetically modified foods that are sold on the Chinese market are safe, according to the Ministry of Agriculture.

China has established a safety supervision system that covers the complete chain of GM products, including research, production and trading, the ministry said.

The ministry will cooperate with other departments to improve legislation concerning GM products and their testing technologies to ensure the safety of GM products, the ministry said in a reply to a March proposal by 10 members of China's top political advisory body on improved safety management of GM foods.
