The World Bank said China would remain the driving force behind regional economic activity even as it forecast the country’s economic growth would slow to 8.7% in 2011, Dow Jones reported. It said China’s economy probably grew 10% in 2010, up from 9.1% in 2009. The bank’s annual Global Economic Prospects report predicted that exports of materials and semi-finished goods to China for processing and re-export would strengthen in the coming year. Net exports are likely to contribute 0.5-1 percentage point to China’s GDP, compared with 2.2 percentage points in 2010, the report said. China’s stimulus program contributed 1 percentage point to GDP growth last year, according to World Bank calculations.
