Is China taking social monitoring too far?

Millions of people are punished for alleged bad behaviour under a government monitoring scheme in China.

Millions of Chinese people have been banned from travelling on planes and trains as the government in China expands its social credit programme that ranks people's trustworthiness.

Last year, more than 17 million people with low scores were barred from buying plane tickets, and another five million were not allowed on high-speed trains.

Four million companies have been blacklisted for "untrustworthy conduct" for a number of activities, including bidding for projects, taking part in land auctions and issuing corporate bonds.
