Chinese customs said on Friday that it would continue import bans on food from about 20% of Japanese prefectures, citing food safety concerns following Tokyo's decision to discharge nuclear-contaminated water from the crippled Fukushima plant into the ocean, reported Nikkei. 

On Tuesday, the International Atomic Energy Agency (IAEA) concluded that Japan's plans to release radioactive water from Fukushima into the Pacific Ocean are consistent with international safety standards. However, that didn't sit well with Chinese authorities. 

China, the largest buyer of Japan's seafood exports, said it would increase monitoring of edible products from Japan and continue bans on seafood imports from 10 prefectures. The General Administration of Customs said this is a move to prevent contaminated food from hitting Chinese supermarkets.
