The Chinese government is obtaining blood samples from up to 70 million – 10% of all men and boys – as the high-tech surveillance state builds a ‘DNA Skynet’ of the country’s 700 million males. Any individual who refuses to give blood samples risks his family being barred from benefits such as travel, fast internet connection and hospital treatment. The powerful genetic mapping tool, which is being compiled from samples collected since 2017, will join up with China’s existing countrywide video-surveillance network. The system will be capable of tracking every male relative of any individual man just from a sample of his genetic material, such as skin or hair. Only 5-10% of the male population needs to be sampled in order to build a complete genetic map, because one sample unlocks the identity of all related males.
