An anti-corruption official in Hunan province has claimed that the China Food and Drug Administration and the Chinese Pharmacopoeia Commission have engaged in corrupt deals with "interest group(s)".

Lu Qun, an official at the corruption prevention office of Hunan's Commission for Discipline Inspection, said the CFDA "endorsed interest group(s)" and "caused huge economic losses".

He made the claim on his Sino Weibo account on Tuesday, but did not provide evidence to back it up.
