China on Friday said it would "gradually resume" importing seafood from Japan after imposing a blanket ban in August last year over the release of water from the disabled Fukushima nuclear plant.

"China will adjust relevant measures based on scientific evidence, and gradually resume imports of Japanese aquatic products that meet regulatory standards," a Foreign Ministry statement said.

The two sides recently conducted "multiple rounds of consultations" on the discharge of water from the stricken Fukushima Daiichi nuclear power station, the ministry said.

It said Japan had committed to "fulfilling its obligations under international law, doing its utmost to avoid leaving [a] negative impact on human health and the environment, and conducting continuous evaluations of the impact on the marine environment and marine ecosystems".

In late August 2023, Japan began discharging treated contaminated water from the Fukushima plant into the Pacific Ocean in an operation it insists was safe, a view backed by the UN's atomic agency.

Beijing strongly criticised the move and banned all Japanese seafood imports.

The Foreign Ministry said on Friday that Tokyo welcomed the establishment of a "long-term international monitoring arrangement within the International Atomic Energy Agency framework covering key stages in the discharge of the nuclear-contaminated water".

"Both sides agree to continue to have constructive, science-based dialogue with a great sense of responsibility for the ecosystem, the environment, and human life and health," it added.

Around the same time as the announcement, Japanese Prime Minister Fumio Kishida said Tokyo had "informed the Chinese side of its readiness to carry out additional monitoring of the... treated water, while the Chinese side has decided to... steadily restore imports of Japanese fishery products that meet certain standards".
