That seems like the short-sighted view that all our previous governments have taken. I think we need to shift to the value added market from simply supplying raw material. Remember when Japan wanted all our coal? We (government)built roads, rail lines, mines and a port to facilitate getting our product to them. Next thing we know there is a glut of coal and we are subsidising the now discounted product! Literally paying them to take it.
Natural resources are finite. They can only play suppliers off against each other for so long. Remember how OPEC started? If the country ever got its crap together and started to say " we'll sell you lumber, but if you want logs, look elsewhere" we'd be better off as a nation.
It wouldn't be easy to change,and who knows if it's even possible with the free trade deals we signed, but let's be honest, we export jobs with the raw materials! As a nation we seem to be interested in the quick buck, rather than the longtime game.
In the short term resource customers can go elsewhere. But by doing this they will eventually drive up prices and deplete availability, making our resources even more valuable when they come back. And they will come back.
Funny how we own a finite supply of resources that the world needs, yet they get to call the shots? OPEC was a great example of what resource producers could accomplish when they said "enoughs enough".
