China will establish a national population database linked to ID information and credit records, state media reported late Monday, as part of a larger push to beef up surveillance and security in response to violent unrest.

China has already taken a series of measures to prevent attacks by extremists, including plans for an anti-terrorism law that would give the government broader surveillance powers and offering to pay for tips about violent plots.

The latest steps also include assigning more security forces to public transport, including buses, trains and subways, as well as to schools, financial institutions and hospitals, the official Xinhua news agency reported, citing a statement issued by the ruling Communist Party's Central Committee and the State Council, China's cabinet.
