The Democratic Republic of the Congo will begin enforcing a long-delayed law requiring mining companies to transfer part of their ownership to Congolese nationals from July 31, the government said. This is despite concerns from major copper and cobalt producers over its impact on the sector.

The 2018 mining code requires companies to allocate 10% of their equity to Congolese nationals, including 5% for employees. However, no mining company has complied, citing uncertainty over how the measure would be implemented.

The mines ministry said the July 31 deadline remains in place following talks with mining companies. Companies were previously warned they could face sanctions if they fail to comply, although the government has not specified what those penalties would be.

DR Congo, the world's largest cobalt producer and second-largest copper producer, is among a growing number of African countries seeking a larger share of revenue from their mineral wealth. Authorities said an ad hoc committee will finalize technical amendments to the implementation decree before it is signed.
