China has rebounded from the global slump with vigour. In the second quarter, its official figures showed year-on-year gross domestic product growth of 7.9 per cent. Those who doubt the quality of China’s macroeconomic statistics can check its physical statistics: in June, electricity production increased 5.2 per cent, reversing the falls of the previous eight months. It is almost certain that China’s GDP will grow more than 8 per cent this year.
