CHINA has refused docking to the MOL Presence after "abnormal" amounts of radiation were detected on the deck of the ship's surface containers, Bloomberg reports.

The 6,350-TEU Japanese ship had passed within 124 kilometre of Fukushima prefecture, site of the crippled Daiichi nuclear power station, and arrived in Xiamen before being asked to depart.

Concerns about radiation have disrupted shipping from Japan, with the country's coast guard advising vessels to keep at least 30 kilometres from the affected area.

China's General Administration of Quality Supervision, Inspection and Quarantine has also banned imports of dairy products, fruit, vegetables, seafood and other "water products" from five areas near to Fukushima prefecture.
