The Chinese final HSBC manufacturing purchasing managers' index (PMI) rose to 49.4 in June from 49.2 in May, down from the preliminary estimate of 49.6.

A reading above the 50 mark indicates expansion, a reading below 50 indicates contraction.

"The final reading of the HSBC China Manufacturing PMI pointed to a further decline in the health of the manufacturing sector in June. This was predominantly driven by the sharpest rate of job shedding across the sector since early-2009, while output also fell slightly on the month," Markit Economics economist Annabel Fiddes said.
