Tencent leads Hang Seng lower ahead of likely U.S. rate hike

Dec 12 (Reuters) - Hong Kong stocks dropped on Tuesday, as index heavyweight Tencent slumped over 3 percent, and declines in other technology shares also weighed on sentiment.

Investors are wary about higher borrowing costs ahead, with the U.S. Federal Reserve widely expected to raise interest rates this week. The Hong Kong dollar is pegged to the U.S. dollar and interest rates there tend to move in tandem with those in the United States.
