"To control food possibly affected by radioactivity, we asked Japan's import-export companies to provide certificates of radioactive safety for their food, and they agreed with our proposal," said Nguyen Cong Khan, director of the Ministry of Health's Food Administration agency.

He was quoted by the Vietnam News.

Countries across the world have restricted Japanese food imports or sought radiation-free certification after radioactive steam leaked from the earthquake-damaged Fukushima nuclear plant.

Vietnam has not banned any food imports from Japan, foreign ministry spokeswoman Nguyen Phuong Nga told reporters on Thursday.
