Glencore has agreed to pay $180mn to the Democratic Republic of Congo to cover claims arising from alleged acts of corruption over 11 years, the latest settlement that the mining company has reached with authorities over its conduct.

Including the new settlement, Glencore has this year agreed to pay more than $1.66bn to authorities around the world following investigations into its business practices. Glencore, one of the largest mining companies in the world by revenue, says it has undertaken a compliance overhaul so that the practices identified by the investigations no longer take place.

The Swiss-based group pleaded guilty in May to bribery and market manipulation following a co-ordinated investigation by US, UK and Brazilian authorities. It agreed a settlement with US authorities of more than $1.1bn, and accepted a US legal monitor who is expected to begin work shortly.
