BEIJING - Chinese police have detained more than 1,900 people suspected of making or selling fake drugs in a nationwide bust.

Also, 1.16 billion yuan ($182 million) worth of fake medicine and related trademark logos, packages and instruction manuals have been seized, according to a statement from the Ministry of Public Security on Sunday.

The ministry said on the basis of previous investigations, more than 18,000 police were mobilized on July 25 to strike against gangs involved, in order to crack down on the industrial chains and circulation channels of fake medicines.
