China's growth slowed for a sixth quarter to the weakest pace since the global financial crisis, putting pressure on Premier Wen Jiabao to boost stimulus to secure a second-half economic rebound.

Gross domestic product expanded 7.6 percent last quarter from a year earlier, the National Bureau of Statistics said today in Beijing. The pace, a three-year low, compares with an 8.1 percent gain in the previous period and the 7.7 percent median forecast of economists. Industrial production increased at a slower pace in June while retail sales growth decelerated.

Today's data painted a mixed picture from a pickup in fixed-asset investment that could signal the economy is stabilizing to the warning sign that electricity output failed to increase in June from a year earlier. Singapore reported an unexpected economic contraction as China's slowdown undermines a global recovery already threatened by Europe's debt crisis and limited U.S. job growth.
