What happened
People who asked not to be named said that an early-week enforcement push against illegal mining resulted in authorities taking into custody roughly 300 Chinese nationals employed in the Democratic Republic of Congo's copper heartland. Most of the arrests were in Kolwezi, the country's mining hub.
Some of the people said agents from Congo's National Security Council and its immigration service took part in the operation. They also said the Chinese embassy in Kinshasa stepped in and that some of the workers were later released. Requests for comment went unanswered by the embassy as well as by Congo's mining ministry, the immigration authority, and the presidency.
Why authorities acted
According to some of the people familiar with the matter, the workers were detained on allegations they took part in illicit mining on concessions owned by other firms. Chinese companies dominate Congo's copper production, and the detentions were described as part of a broader clampdown on unauthorized extraction.
The wider backdrop
A wave of predominantly Chinese investment has driven growth in Congo's copper sector in recent years, enabling the country to triple output since 2015 and overtake Peru as the No. 2 producer worldwide. The surge has also created instability, with artisanal miners - at times backed by soldiers - regularly entering concessions owned by international investors and working there without authorization.
