China’s media regulators will this week launch a new round of their regular campaign against box office fraud.

The move, reported by state news agency Xinhua, will be a three stage operation organized by the State Administration for Press Publishing Radio and Television.

“Producers suffer badly from box office cheating as their profits rely heavily on theatrical box office sales,” said Zhang Hongsen, film bureau head of the SARFT, according to Xinhua.

China’s theatrical box office grew an official 49% last year to $6.7 billion. And more than half of ticket sales are now online, particularly through online apps. But the pace of growth and the arrival of numerous small, inexperienced theater operators creates plenty of opportunity for cheating.

SAPPRFT said that it has developed an app to help cinema-goers identify fake tickets.
