More signs of slower economic growth in China are creating worries that the world's second-largest economy may curb its huge appetite for commodities.
HSBC Corp. said Thursday that a preliminary survey of purchasing managers showed China's manufacturing sector continued to slow in September but the pace of the slowdown appeared to be stabilizing.
Separately, financial data company Markit said its purchasing managers' index for the 17 countries that use the euro currency declined more than expected in September. That indicates Europe appears headed for a deepening recession. Europe is China's biggest export market.
China is a huge importer of raw materials such as copper, oil and coal for use in its manufacturing sector. It also has been importing huge quantities of U.S. soybeans to help feed its population. If China's economy continues to slow, traders are worried that demand will drop, analysts said.
