Tax authorities in the Democratic Republic of Congo seal off offices linked to a Glencore Plc-owned copper mine, escalating a dispute over payments the state says are owed. Both reports say the action involves closing the mine’s offices in the country as part of the tax authorities’ response to an outstanding payment issue. The companies’ position is not detailed in the available summaries, but the reports describe the move as a step up in a disagreement between the tax agency and the miner regarding amounts due to the government. The dispute centers on payments allegedly owed to the state, according to the outlets. By sealing the offices, the authorities take a more direct enforcement measure that can affect operations and administrative functions at the mine. The reports do not provide additional information on the specific tax assessment, the amount claimed, or any timeline for negotiations or resolution.
