Hong Kong's benchmark stock index dipped on Wednesday, snapping a five-session winning streak, amid lingering worries about China's economy. The Hang Seng index fell 0.3 percent, to 20,760.98. The China Enterprises Index was unchanged at 8,708.29 points. China's manufacturing activity showed signs of steadying in May but remained weak amid soft demand at home and abroad, suggesting the world's second-largest economy is still struggling to regain traction.
