Chinese Foreign Ministry spokeswoman Mao Ning told reporters in Beijing Friday that China remains entirely opposed to Japan “unilaterally starting the ocean discharge.”

She said the blanket ban will not be lifted immediately but will be repealed slowly as Chinese officials begin the additional monitoring process.

Japan announced last August it would begin a gradual release of treated radioactive wastewater collected from the destroyed Fukushima nuclear power plant into the ocean.

Chinese officials the same day announced a total ban on Japanese seafood imports despite claims the treated water posed no threat.

Last September, Chinese seafood imports from Japan fell 67.6% on a year-over-year basis.

Tokyo has consistently maintained releasing the wastewater does not pose a health risk in seafood.

The country on Friday agreed to allow China to conduct further monitoring of the discharged water, under supervision of IAEA officials.

“China has begun adjusting its import restrictions and will steadily resume imports of Japanese seafood that meet safety standards,” Japanese Prime Minister Fumio Kishida told reporters at a news conference Friday.

“Our country’s position that the restrictions should be promptly lifted has not changed, and we will continue working toward full removal of the restrictions.”

Kishida said China and other countries in the region are expected to take part in the additional monitoring.
