Others flagged the fact that the manufacturing sector remains stuck in contraction, and has been for five months now.

"The main thing we'll be taking from this is the fact that it does remain below that threshold between expansion and contraction so number of 49.7 might have beat expectations still is consistent with contracting manufacturing sector in China," Hamish Pepper, currency strategist with Barcays.

Beijing in recent months embarked on a series of so-called "mini-stimulus," ranging from infrastructure spending to lower taxes for small businesses, in a bid to arrest a slowdown in the world's second largest economy.

According to John Taylor, professor of economics and finance at the National University of Singapore, while the data is reassuring, it won't be smooth sailing from here given China's push to rebalance away from investment and exports and towards domestic consumption.

"I think generally speaking there are going to be some more adjustments in China – the reforms are important, they're going to have some adjustments. I think it's good news but this is one piece of information along with all the other stuff that's coming out," Taylor said.
