This year China will need enough ore to make enough steel to build high-rise apartments for 19 million new urban migrants, make 8.5 million cars, complete 17 major city airports and roll out tens of thousands of kilometres of railways, tunnels, bridges and elevated highways. As Phil Mitchell, Rio Tinto's iron ore development manager, likes to put it: "China is building from scratch a city the size of Brisbane every month."

And yet this country of 1.3 billion people is only now entering the most resource-intensive phase of its urbanisation and industrialisation — a revolution that could keep rolling on for another three decades.

Car production is rising by 46 per cent a year. Fixed-asset investments (such as factories and bridges) account for nearly half of China's gross domestic product and are growing at 26 per cent.

Figures like these explain why spot (non-contract) prices for iron ore and coal — the two core ingredients of steel — have risen by 71 per cent and 38 per cent respectively this year. China's iron ore imports have risen eightfold in just eight years. China has doubled coal consumption in five years, turning it from exporting to importing and pushing up prices paid by Australia's key coal customers in Japan and Korea.

Steel and iron ore supply may be increasing, but demand is shooting through the roof. The good money is on a price rise in the vicinity of 50 per cent this year — enough to almost guarantee that Australia sails through any economic downturn in the United States.
