Russia's farm ministry said it has partially lifted a ban on seafood imports from Japan imposed in the wake of the Fukushima No. 1 nuclear crisis.

A total of 23 fish processing companies in Aomori Prefecture will now be allowed to ship their products to Russia, but the trade embargo will remain for companies in seven other prefectures, the ministry said Tuesday.

Russia made the decision based on preliminary results of a study carried out by the International Atomic Energy Agency in February. The fact that Aomori Prefecture is relatively far from the Fukushima No. 1 nuclear plant played a role in the decision.
