The Hang Seng Index gained 204.32 points, or 0.89 percent, to open at 23,238 points on Wednesday.

Elsewhere, Australian consumer prices dipped month-on-month in January, dragged lower by a slowdown in housing costs and a drop in holiday travel, an outcome that should help reassure policymakers that inflation is heading in the right direction.

Data from the Australian Bureau of Statistics on Wednesday showed the monthly consumer price index (CPI) fell 0.2 percent in January from December, when it rose 0.8 percent. The annual pace held at 2.5 percent, matching market forecasts. (Agencies)
