China’s Stocks Retreat Most in a Month as Economic Growth Slows

China’s stocks fell, sending the benchmark index to its biggest loss in almost a month, after the economy grew at the slowest pace in two years and Germany damped expectations for a fast resolution to Europe’s debt crisis.

PetroChina Co. and Jiangxi Copper Co., the nation’s largest oil and copper producers, led declines by commodity producers after gross domestic product expanded less than analysts’ estimates. China Vanke Co., the biggest developer, slid 2 percent after home prices gained in fewer than half of 70 cities as sales eased. Sinohydro Group Ltd., the nation’s largest builder of hydroelectric dams, jumped 17 percent in China’s biggest initial public offering this year.
