Russia mulls joining China in banning Japanese seafood imports

Japan started releasing the water from the plant into the ocean last month, drawing strong criticism from China. In retaliation, China imposed a blanket ban on all aquatic imports from Japan.

Russian food safety watchdog Rosselkhoznadzor on Tuesday said it had discussed Japanese food exports with its Chinese counterparts. Russia is one of the biggest marine product suppliers to China and is seeking to increase its market share.

"Taking into account the possible risks of radiation contamination of products, Rosselkhoznadzor is considering the possibility of joining with Chinese restrictions on supplies of fish products from Japan," Rosselkhoznadzor said in a statement. "The final decision will be made after negotiations with the Japanese side."

So far this year, Russia has imported 118 tonnes of Japanese seafood, the regulator said.

Rosselkhoznadzor said it had sent a letter to Japan on the need to hold talks and requesting information on Japan's radiological testing of exported fish products by Oct. 16, including tritium.

Japan will scrutinise Tuesday's announcement by Russia, the top Japanese government spokesperson Hirokazu Matsuno said on Wednesday.

Japan says the water is safe after being treated to remove most radioactive elements except tritium, a radionuclide difficult to separate from water. It is then diluted to internationally accepted levels before being released.

Japan has said criticism from Russia and China was unsupported by scientific evidence.

"We strongly ask Russia to act based on scientific evidence," Matsuno told a Wednesday press conference, adding that Russia was a member of the International Atomic Energy Agency (IAEA)'s Fukushima expert team, which in July greenlighted the water release plan.

On Monday, in its latest report on water testing, Japan's Ministry of Environment said analysis results of seawater, sampled on Sept. 19, showed the tritium concentrations were below the lower limit of detection at all 11 sampling points and would have no adverse impact on human health and the environment.

Russia has also detected no irregularities in marine samples used for tests in Russian regions that are relatively close to where the treated water was released, Rosselkhoznadzor's far eastern branch said on Tuesday, Interfax reported.
