(Nature) – In September 2019, four researchers wrote to the publisher Wiley to “respectfully ask” that it immediately retract a scientific paper.

China had already been internationally condemned for its heavy surveillance and mass detentions of Uyghurs in camps in the northwestern province of Xinjiang — which the government says are re-education centres aimed at quelling a terrorist movement. According to media reports, authorities in Xinjiang have used surveillance cameras equipped with software attuned to Uyghur faces.
