In China, official manufacturing PMI for July stood at 51.4, compared to a Reuters forecast of 51.6. The July figure was also below June's reading of 51.7. Meanwhile, the official services PMI came in at 54.5 for July, compared to the 54.9 seen in June.
While manufacturing PMI data tends to be more closely watched, China's pivot toward domestic consumption and away from investment-led growth means the services sector accounts for a bigger slice of the mainland economy.
"China's PMIs suggest further expansion, albeit with measured acceleration," said Mizuho Bank FX strategist Chang Wei Liang in a Monday morning note.
"This is consistent with a pick-up led by electronics and infrastructure-related activities. Nonetheless, the recovery is somewhat uneven."
