Hong Kong stocks fall

Hong Kong markets fell on Tuesday, weighed down by energy shares as oil prices dropped on doubts that producer cartel Opec would hammer out an output cut this week. Investors' risk appetite was also curbed by a lacklustre performance in global equity markets overnight. The benchmark Hang Seng index ended down 0.4 percent at 22,737.07 points, while the China Enterprises Index lost 0.3 percent to 9,846.21. Sentiment was also dampened by falling coal prices. China's thermal coal futures lost nearly 3 percent to a 5-1/2-week low. Index heavyweight China Shenhua Energy Co Ltd slid 1.5 percent.
