Boris Johnson’s diary: Amid the China hype, remember Japan

Frankly I don’t know why the British media made such a big fat fuss last week when I accidentally flattened a ten-year-old Japanese rugby player called Toki. He got to his feet. He smiled. Everyone applauded. That’s rugby, isn’t it? You get knocked down, you get up again. And yet I have to admit that I offered a silent prayer of thanks that I didn’t actually hurt the little guy. They aren’t making many kids like Toki these days; in fact they aren’t making enough kids at all.

If you want proof of the rule that nobody knows anything, look up a 1988 bestseller called Yen! Japan’s New Financial Empire and its Threat to America. It was by Daniel Burstein, an American financial journalist, and the gist was that the yen was about to supplant the dollar as the world’s reserve currency; that Japan was buying up key American assets and flexing its muscles, with a frightening martial revanchism, with a view to taking over the world.
