China will ban the import of food from 10 Japanese prefectures for safety reasons, customs authorities said on Friday.

The nation will also strictly review the documents for food, especially aquatic products, from other parts of Japan, customs said in a statement.

It added that it will continuously strengthen the detection and monitoring of radioactive substances to ensure the safety of food imported from Japan.

China was the biggest buyer of Japanese seafood exports last year, even though it is among several countries that restrict imports from some Japanese regions because of the nuclear accident.

The nation is also the fiercest critic of Japan's planned release of the water saying it threatens marine life and human health. (Reuters)
