Asia is the world’s largest continent and home to 4.4 billion people. But its story is disproportionately about China’s economic growth. Beijing’s official statistics are notoriously unreliable, but by most reckonings, China became the world’s largest economy (measured by purchasing power parity, PPP) in 2014. What isn’t so well known is how astonishingly fast the end came for the 140-year reign of the American economy as the world’s largest. According to numbers Rachman cites, China was just 12 percent of the size of the US economy in 2000 and only half as big as late as 2011. Such meteoric growth has been enough to lift hundreds of millions out of poverty, finance the US deficit, and still allow China to increase its military spending at double-digit rates every year for two decades.
