China’s state ore buyer freezes some Rio Tinto talks

China's state-owned iron ore purchasing agency has directed some domestic steel mills to suspend negotiations with Rio Tinto ↗ 1.54% over shipments from September, Reuters reported on Thursday, marking the latest escalation in Beijing's campaign to consolidate bargaining power over the world's largest iron ore producers.miningweekly+1

Consolidating Control

China Mineral Resources Group (CMRG) has increasingly wielded purchasing restrictions as leverage during annual contract negotiations with Australian miners. The directive to halt talks with Rio Tinto is aimed not only at extracting better terms from the miner but also at pressuring Chinese steel mills that have retained independent negotiating rights to cede them to CMRG, according to two traders and an analyst cited by Reuters.reuters

Wood Mackenzie estimates that CMRG already negotiates for more than half of China's annual iron ore imports, which exceed 1.2 billion metric tons per year. By preventing mills from settling cargo volumes and shipment dates independently, CMRG can increase the tonnage under its centralized purchasing system and strengthen its hand against suppliers.thedeepdive+1

Pattern of Pressure

The move follows similar confrontations with BHP ↗ 2.25%, Fortescue ↗ 3.08%, and privately held Hancock Prospecting. BHP faced progressive purchasing bans on some products through late 2025 and early 2026 before restrictions were lifted following a visit by its then-incoming CEO Brandon Craig in April. A senior Fortescue executive said last week that CMRG's actions were undermining the stability of China's iron ore supply.miningweekly

Rio Tinto had been considered somewhat insulated from such tactics given that China's state-owned Chinalco is its largest shareholder and leads the consortium partnering with it on the Simandou iron ore project in Guinea. However, Rio Tinto's iron ore chief executive Matthew Holcz acknowledged this week that negotiating leverage has shifted away from producers as growing supply has brought the market closer to balance.reuters+1

Geopolitical Dimensions

Australia supplies more than half of China's iron ore imports, making it the country's largest source of the steelmaking ingredient. Australian miners and their lobbyists have asked Canberra to push back against Beijing's tactics, including floating the idea of a single selling desk for Australian iron ore exports. But at least one miner noted that the Australian government, still working to repair relations after China's unofficial commodity export bans between 2020 and 2023, may be reluctant to take up the fight.miningweekly
