A series of marketing presentation slides reviewed by the Washington Post found Huawei had a role in developing surveillance projects created in a partnership with other Chinese companies.
They included analysis of voice recordings, monitoring detention centres, tracking locations of political individuals of interest, police surveillance in the western Xinjiang region, and corporate tracking of employees and customers.
While the slides did not specify who the presentations were for, the report said some of them showcased surveillance functions specific to police or government agencies, which suggests Chinese government authorities may have been the intended audience.
