China's gross domestic product figures are among the world's most closely watched since they can move markets or boost hopes of an imminent recovery.
But the latest set of first-half numbers provided by provincial-level authorities are far higher than the central government's national figure, raising fresh questions about the accuracy of statistics in the world's most populous nation.
GDP totalled Rmb15,376bn ($2,251bn) in the first half, according to data released individually by China's 31 provinces and municipalities, 10 per cent higher than the official first-half GDP figure of Rmb13,986bn published by the National Bureau of Statistics.
