Stock market indexes in Hong Kong soared as investors played catch-up tracking last week's gains in the mainland. 

The Hang Seng index increased 1.8%, and the mainland-focused CSI 300 index decreased 0.1%, amid sustained buying by the state-controlled enterprises on mainland bourses. 

Interim results dominated market sentiment, and Alibaba Group soared 15%, and BOC Hong Kong advanced 7%. 

On the economic front, the official survey of the manufacturing sector activities showed a slight increase in August.

The General Manufacturing PMI increased to 49.4 from 49.3 in July, the National Bureau of Statistics reported on Sunday.

The private sector business activities in the manufacturing sector are facing headwinds from the erratic U.S. trade policy and softer domestic demand. 

The separate survey released by S&P Global showed an increase in business activities.

The RatingDog China General Manufacturing PMI edged up to 50.5 in August from 49.5 in July, amid sustained foreign demand and a rebound in domestic orders.

The private survey of business activities has a larger sample size of smaller businesses and companies engaged in export activities.
