China appears to be laying the groundwork for the broad collection of DNA samples from residents of a restive, largely Muslim region that's been under a security crackdown, rights observers and independent experts said today.
Observers from Human Rights Watch said they've seen evidence of almost USD 3 million in additional purchases related to DNA testing and warned that such a collection program could be used as a way for authorities to beef up their political control.
Since it started collecting DNA profiles in 1989, China has amassed the unique genetic information on more than 40 million people, constituting the world's largest DNA database, according to a study last year by forensic researchers at the China Ministry of Public Security.
Unlike many other countries, China lacks legal protections to guard people's privacy and prevent their genetic information from being misused, said Helen Wallace, founder of the British group GeneWatch.
Xinjiang borders several unstable Central Asian countries, including Afghanistan. It's experienced numerous bombings and vehicle and knife attacks blamed on ethnic separatists from the native Uighur Islamic minority.
In one of the most recent attacks, eight people, including three assailants, were killed in a February knife attack in southern Xinjiang's Pishan County, which borders Pakistan.
Chinese authorities seeking to counter religious extremism among the Uighurs (pronounced WEE-gurs) have taken increasingly aggressive steps to quell the unrest. Those have included mandatory satellite tracking systems for vehicles in some areas, rewards for terror-related tips and prohibitions against women wearing veils and men growing beards.
The official, who gave only her surname, Huang, said a supplier already had been found. In Xinjiang's Sheche County, suppliers were being sought for voiceprint collection systems and 3-D portrait systems, according to a security official surnamed Yin, who declined to give further details.
