Brazilian authorities have suspended the issuance of temporary work visas for BYD in the wake of accusations that some workers at a site owned by the Chinese electric vehicle producer had been victims of human trafficking,

Announcement came days after labour authorities also said they found Chinese workers at factory in Bahia were victims of human trafficking.

BYD has been building the factory with an annual capacity of producing 150,000 cars initially in Brazil, the Chinese EV giant's largest overseas market, as part of plans to start production there.
