Steel’s Transformation: China and Australia’s next horizon of clean steel 

As the global steel sector seeks lower-emissions and higher-value production pathways, clean iron is emerging as a critical link in the next generation of steel trade. Australia and China already form the world’s largest raw material partnership in steel: China’s imports account for nearly half of global trade in key steelmaking inputs, with most of its iron ore coming from Australia. Their clean-energy ties are also deepening, with Australian projects increasingly drawing on Chinese solar, battery, and engineering capabilities. Building on this foundation, a green iron corridor between the two countries could become an opportunity for the next phase of clean industrial cooperation. 

Momentum is growing, but the market has not yet formed. At the high level, both governments have signaled their intent to cooperate on steel decarbonization, while companies have begun joint studies and exploratory cooperation on clean iron. The next step is to translate this shared interest into commercially grounded projects. The challenge is not only technical, but also commercial. Clean iron demand is expected to scale gradually, costs remain above conventional steelmaking routes, and Australia’s clean iron production is not yet cost-competitive to some Chinese provinces today. Coordinated Australia-China cooperation across finance, technology, infrastructure, and offtake can help close this gap and move early projects toward investment readiness. 

This report examines what it would take to turn that opportunity into a viable corridor, with a focus on the subnational dynamics that will shape where trade can emerge first. It identifies where clean iron trade could make commercial sense, what each country stands to gain, and how cooperation can close the cost gap. The report finds that Australia and China have complementary reasons to move together: Australia can underpin higher value-added exports by producing clean iron onshore, while China can support low-emissions steel production in coastal provinces and scale its clean industrial technologies in international markets.  

By anchoring lighthouse projects, activating reciprocal demand, and cutting costs through finance, technology, infrastructure, and engineering partnerships, the two countries can move from principles to projects and establish a green iron corridor that delivers benefits across the full value chain.
