A broader analysis by The Economist finds that China has already overtaken America on well over half of 21 different indicators, including manufacturing output, exports and fixed investment. The chart below predicts when China will surpass America on the rest. By 2014, for example, it could be the world’s biggest importer and have the largest retail sales. America still tops a few league tables by a wider margin. Its stockmarket capitalisation is four times bigger than China’s, and it spends five times as much on defence. Even though China’s defence budget is growing faster, on recent growth rates America’s will remain larger until 2025.
