In afternoon trade Hong Kong climbed 1.77 percent. Tokyo ended up 1.37 percent, or 184.06 points, at 13,572.92, while Sydney closed 1.03 percent, or 53.3 points, higher at 5,188.3.

Data Saturday showed China's official purchasing managers' index (PMI) of manufacturing hit 51.0 last month, up from 50.3 in July and the best reading since April last year. Anything above 50 indicates growth, while anything below signals contraction.

The results follow a slew of recent upbeat data that suggest a slowdown in the world's number two economy and key driver of global growth may have come to an end.
