Hong Kong - Asian markets edged up on Monday following a record close on Wall Street at the end of last week, while analysts said data indicating sluggishness in the Chinese economy could prompt fresh stimulus from Beijing.

China said Monday that its official purchasing managers index (PMI) of manufacturing activity slipped to 51.1 last month. That is down from 51.7 in July, a more than two-year high and the first decline since February.
