Police in Shanghai are offering up to 500,000 yuan ($77,000) for tip-offs related to terrorist or extremist activities.
The rewards are "to intensively guard against and crack down on terrorism and maintain the security of the city and stability of the society," according to a statement from the public security bureau.
The incentives, announced yesterday, will be on offer until April 13 next year.
Jiang Ping, who leads a city anti-terrorism workforce, said: "We will enhance our preemptive measures and combating capabilities against terrorist activities and heighten citizens' awareness of anti-terrorism."
The bureau said it was seeking clues about any activities that could cause panic and undermine public security.
These could include conspiracy to commit explosions, fires, murders and abductions. Threats involving dangerous substances are also covered in the rewards program.
The public are also encouraged to report any information about unusual activities involving the manufacture, trade, transport or storage of firearms, munitions, explosives, illegal knives and dangerous chemicals.
The bureau is also seeking information on people who "instigate hatred, prejudices and violence by distorting religious doctrines and other means and gather people to spread terroristic ideas."
The wide-ranging appeal also encourages tip-offs about people who "design, manufacture, sell, mail or sport emblems, flags, badges, clothes, objects and souvenirs which bear terrorist or extremist content" and who "produce, download, spread, watch, read, listen to or privately store publicity materials relating to terrorism and extremism."
Citizens who have information about people involved in terrorist groups who travel to or entreat others to travel to foreign countries to join terror groups or to be trained by them or those who "establish camps for physical and tactical trainings of terrorists" are also urged to report the information to police.
The police are also looking for clues about those who assist terrorist activities with finance or equipment, transport, weapons, sites, services and technological support.
The bureau said the public can report their suspicions to officers on the street, at police stations or by dialing 110. They can also send text messages to 12110 or e-mail gaj110@shanghai.gov.cn.
The bureau said the size of the reward would be determined by the value placed on the information.
Police said informants could be assured of anonymity, but false alarms or libel would be punished.
China's Anti-Terrorism Law came into effect at the beginning of the year. Apart from defining "terrorist activities," it also stipulated that people who contribute to anti-terrorism efforts deserved rewards.
