HONG KONG, Nov 22 (Reuters) - Hong Kong shares could start higher on Thursday, with a preliminary survey of November manufacturing activity in China expected at around 0145 GMT that could offer more clues on the state of the world's second-largest economy.
The U.S. Thanksgiving holiday could keep turnover in Hong Kong muted, with price movements on the day magnified by low volume.

Elsewhere in Asia, Japan's Nikkei was up 0.9 percent, while South Korea's KOSPI was up 0.8 percent at 0053 GMT.
