A mixed bag of Chinese economic data this week has unnerved global markets and clouded the outlook for China's economic growth, days before the release of the country's quarterly gross domestic product figures.
Global markets rose on Friday after official data showed China's factory output prices grew in September for the first time in almost five years, but a day earlier, stocks in Europe and on Wall Street were hammered by an unexpectedly poor Chinese trade report for the same month.
Exports for September slumped 10 percent from a year earlier, despite the yuan's depreciation in the past year. Imports unexpectedly fell, after ticking higher in August, raising questions over the resilience of domestic demand.
