China will launch a campaign to keep terrorism-related video and audio information off the Internet, on grounds that publicity encourages terrorists to commit more violent acts, the State Internet Information Office said.

The office announced the move in a video conference attended by heads of provincial Internet information offices.

Almost every terrorist involved in recent violence, including the March 1 knife-wielding assailants who killed 29 civilians in Kunming, Yunnan province, and the May 22 bomb attack that killed 43 in Urumqi, capital of the Xinjiang Uygur autonomous region, once listened to or watched videos and audio files related to terrorism, an official with the State office said at the conference. The official did not want to be named.
