China’s MMG Bemoans Congo Cobalt Curbs That Threaten Investment

China’s MMG Ltd. wants more clarity on the Democratic Republic of Congo’s cobalt-export policy after the state-controlled miner received a disappointing quota, as questions mount over how curbs have been imposed.

Congo, the top producer of the battery metal, first banned exports in February 2025 to reduce a glut and capture more value from its output. It followed that with strict quotas from October, which for most companies are mainly calculated on a pro-rata basis according to their exports in the three years to the end of 2024. The restrictions have slowed shipments and boosted prices.
