Cobalt is an essential component of batteries for smartphones and electric cars. Around 60% of it comes from just one country, DR Congo – and most of the metal is exported to China.

Meanwhile, around a quarter of the cobalt extracted in DR Congo is sold through the black market. This report is from our France 2 colleagues, with Erin Ogunkeye.
