The official manufacturing purchasing managers’ index rose to 50.3 from 50.0 in May, coming in a touch ahead of market expectations for a reading of 50.1.
A reading above 50.0 indicates expansion, while a reading below signals contraction.
The non-manufacturing PMI, which covers construction and services activity, ticked up to 50.2 in June from 50.1 in May. Economists had been expecting a dip back into contraction territory at 49.9.
Lynn Song, chief economist, Greater China at ING, said: "China’s purchasing managers’ index data came in slightly stronger than downbeat expectations, but it doesn't suggest a major turnaround in June and a second-quarter slowdown is still likely.
"Sluggish domestic demand could potentially prompt further policy support, with markets looking ahead to July's Politburo meeting."
