Chinese newspapers reported on Friday that a ban on disco music in private rooms of nightclubs and karaoke bars have taken effect in an attempt to control the rise in illegal drug activity at Beijing's entertainment venues.

The Beijing Times newspaper said, "Because many drug takers regularly dance and go crazy to upbeat 'disco' music in private rooms, police have specially requested karaoke machines not have this music."

The Beijing News said authorities have asked club owners to get rid of disco and "other vulgar entertainment" from karaoke machines in private rooms. This is in compliance with a "responsibility agreement" drawn up by the police.

Reuters reports, the agreement was signed by over 1,100 club owners in response to the rise in drug trafficking and violent crime involving customers and staff.

The Beijing News also said on Thursday that police would conduct random urine tests for staff in Beijing's clubs for identifying employee addiction to drugs as a major link to drug trafficking.
