China Mineral Resources Group Asks Some Steel Mills to Suspend Negotiations with Rio Tinto
Miles Bennett
China Mineral Resources Group (CMRG) has told some steel mills to stop negotiating September iron-ore shipments with Rio Tinto — extending its pricing pressure campaign to the world's largest iron-ore producer, previously seen as shielded by Chinese state ownership ties.
What does halting negotiations actually achieve?
CMRG told some mills not to finalise purchase volumes, cargo specifics, or shipping dates with Rio Tinto from September onward.
This means → the freeze targets the details, not the buying itself — pulling bargaining chips back from individual mills.
The goal is direct: force mills that have not yet ceded purchasing authority to CMRG to hand it over, expanding the state trader's scale and leverage.
How much clout does CMRG already hold?
Wood Mackenzie estimates CMRG now handles more than half of China's annual iron-ore imports.
It has already applied similar pressure to BHP, Fortescue, and Gina Rinehart's Hancock Prospecting.
In plain terms = all four of Australia's major iron-ore suppliers are now on CMRG's pressure list. Rio Tinto is the last to be targeted.
Why was Rio Tinto considered 'protected' until now?
Rio's largest shareholder is Chinese state-owned Chinalco, which also co-leads the Simandou iron-ore project in Guinea with Rio.
This reflects the market's prior assumption: an equity link plus a flagship joint venture would give Rio a degree of immunity.
But Rio's iron-ore chief Matthew Holcz said this week that rising supply is rebalancing the market, weakening miners' bargaining position — in other words, the shield is thinning.
How are miners and Canberra responding?
A Fortescue executive said last week that CMRG's actions are undermining the security of China's own iron-ore supply.
Australian miners have asked Canberra for support, including a proposal for a unified selling platform for the country's most important commodity export.
This means → the miners want to match concentration with concentration. But at least one miner judges that Canberra, focused on repairing ties with Beijing, is unlikely to intervene in the near term.
