In mid-2012, Donald Trump fired off this tweet: “The concept of global warming was created by and for the Chinese in order to make US manufacturing non-competitive.”
Apart from its sheer absurdity, one of the most striking things about Mr Trump’s assertion is how similar it sounds to the paranoid ravings of Chinese nationalists, who blame almost everything on the CIA and evil, imperialist America.
With admirable patience, Chinese officials have pointed out in recent weeks that global discussions on climate change were started by the Reagan administration in the 1980s at a time when China did not even acknowledge the existence of pollution within its borders.
