China has suspended beef imports from the Australian firm John Dee Warwick after it detected a banned substance in beef loin from the company, the country's General Administration of Customs said in a statement on Thursday.

The products were not allowed to enter China after the detection of chloramphenicol, a substance banned in both China and Australia, the statement added. 

The customs administration has requested a full investigation of the company and required that the Australian side provide feedback information within 45 days.
