China's Jinjiang Group is in the spotlight after Brazil's labour authorities said workers at a factory it is building for electric vehicle maker BYD were victims of human trafficking working in "slavery-like conditions".

The 163 Chinese workers found by Brazil’s labor ministry in what it described as “slavery-like conditions” at a factory construction site owned by Chinese electric vehicle producer BYD 002594.SZ have been removed and taken to hotels,

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.
