An Australian university is calling for a controversial facial recognition study by an ex-faculty member to be retracted by its publisher.

The research, which was co-funded by China, used facial recognition software to identify members of the Uyghur minority group.

But Curtin University said the study breached ethics guidelines, with the subjects not giving informed consent.

The publisher, Wiley, said it was looking again at the research.

In a statement, Wiley said it had previously investigated the study and was "now reviewing the matter again taking into account the new information provided by Curtin University".

China has faced multiple allegations of abuses against Uyghurs, including accusations it has committed genocide and forcibly sterilized women.

Human rights groups believe China has detained more than one million Uyghurs in a large network of what the state calls "re-education camps", and sentenced hundreds of thousands to prison terms.

China has denied all accusations it has mistreated Uyghurs.

After Australia's ABC News investigated the study in 2019, human rights groups warned facial recognition technology could be used to persecute minority groups.

The study's author, academic Wanquan Liu, has since resigned and moved to a Chinese university. The BBC has emailed him for comment.

Curtin University said that the research was carried out without its consent, and that it had now strengthened its oversight.

But the chair of the Australian parliament's intelligence and security committee, James Paterson, said he remained concerned.

"It does raise troubling questions about how this research was allowed to be conducted in the first place and why it went undetected for so long," he told ABC News.

China-Australian ties have deteriorated in recent years, with universities a flashpoint.

Chinese pro-democracy students have warned of harassment if they speak out on sensitive issues, while Australia's government has set up a taskforce to combat what it described as "unprecedented levels" of foreign interference.

In a move likely to raise tensions further, US President Joe Biden is set to announce a plan to share advanced technologies with Britain and Australia.
