The Markit/HSBC Chinese manufacturing purchasing managers' index fell to a 28-month low of 48.9 in July, indicating activity was now beginning to contract in the world's second largest economy.
"We expect industrial growth to decelerate in the coming months as tightening measures continue to filter through," Qu Hongbin, HSBC Chief Economist for China, said following the report.
