Iron Ore Price, page-7626

He doesn't seem to consider at all that debt that goes towards real infrastructure like railways, highways and connecting tunnels (where those don't currently exist - and would be part of One Belt, One Road planned development) isn't the same as debt that goes towards inflating existing house prices.

He considers the chinese futures traders could be right (despite seeming to be excessively bullish to much of the rest of the world) to believe the Chinese authorities development plans will be acted upon and that real developments will occur, (he points out cement which isn't traded on a futures market is consistent with that view that real construction is taking place) but not that the Chinese development plans could themselves be economically sensible rather than wasteful spending.

If I could find a reliable place to track cement sales and electricity production I think his article could be useful anyway. Those things should indicate real economic activity.
