China says no abnormalities were found in the second international monitoring of seawater taken near the damaged Fukushima Daiichi nuclear power plant.



An expert from China was among the researchers in the survey. The China Atomic Energy Authority said on Monday it found no abnormal concentrations of radioactive substances from the samples taken in February.



The Chinese authority had also said after the first monitoring in last October that no abnormalities were found in seawater samples.



Japan and China agreed last September that China will resume imports of Japanese marine products in phases. But China set a precondition of its participation in seawater monitoring near the Fukushima Daiichi plant under the framework of the International Atomic Energy Agency and finding no irregularities in samples.



Attention is on whether talks will make progress over China's resumption of imports of marine products from Japan.



A Chinese Foreign Ministry spokesperson said on Monday that no abnormalities in individual analysis does not mean there will be no problem in the future.



The spokesperson suggested that China will request continued international supervision of the release of treated and diluted water from the Fukushima Daiichi plant.



Water used to cool molten fuel at the Fukushima Daiichi plant has been mixing with rain and groundwater.
The accumulated water is being treated to remove most radioactive substances, but it still contains tritium.



Before releasing the treated water into the ocean, the plant's operator dilutes it to reduce the tritium levels to about one-seventh of the World Health Organization's guidance level for drinking water.
