【SMM Nickel Market Flash】Brazil's competition authority, Cade, has initiated an investigation into the planned $500 million sale of Anglo American's nickel operations in the country to MMG Singapore Resources, a subsidiary of China-backed MMG. The probe was launched following a complaint from a competitor, CoreX Holding. This move adds a new layer of complexity to Anglo American's ongoing restructuring efforts. The deal has also drawn concern from the United States over China's growing influence in the global supply chain for nickel, a critical mineral.
