COALMINERS cheered this week when Donald Trump issued an executive order to start unwinding Barack Obama’s flagship climate policies; the new measures include ending a moratorium on the leasing of federal land for mining. “My administration is putting an end to the war on coal,” declared Mr Trump.

And for all the attention on America, much the more important chapter in the tale of coal’s decline is being written on the other side of the world.
