China criticised over biometrics collection in Xinjiang

Human Rights Watch has slammed China for the way it is collecting DNA and biometrics from citizens in its restive Xinjiang province.

Officials are building a database of iris scans and blood types of everyone aged between 12 and 65 in the region, adding to controls in a place some experts called an "open-air prison", the Guardian reported.

The data can be used for "surveillance of persons because of ethnicity, religion, opinion or other protected exercise of rights like free speech", Human Rights Watch said.

Xinjiang has long been subject to tight controls and is home to over 11 million Uighurs, a Muslim Turkic minority. Heavily armed troops in the region are a common sight.

Authorities frequently hold mass rallies in the region to bolster their support in the fight against the Islamic extremists Beijing blames for a series of attacks on government officials and civilians.

But rights groups said most of the violence stemmed from restrictions on religion, culture, language and expression as well as a lack of economic opportunities in the impoverished region.

According to HRW, part of the collection was being done through government-provided medical check-ups and it was unclear if patients were aware that the exam was also designed to transmit biometric data to the police.

"The mandatory databanking of a whole population's biodata, including DNA, is a gross violation of international human rights norms," said Sophie Richardson, China director at HRW.

However, officials in the region claimed the scheme was meant to improve policies aimed at poverty alleviation. They also said it was targeted at "social stability".
