The Hang Seng Index gained 8.46 points, or 0.05 percent, to open at 17,205.42 points on Tuesday.

A reading on US inflation is due on Wednesday, where expectations are for the headline number to have further slowed to an annual 2.6 percent in August. (with additional reporting from Xinhua and Reuters)
