Hong Kong's stock market ended lower on Wednesday with the benchmark Hang Seng Index down 1.63 percent to close at 19,778 points.

China's blue-chip CSI 300 Index and the Shanghai Composite Index both declined 0.9 percent at the close, marking their biggest single-day retreat in nearly two weeks.

Stocks in both Hong Kong and China were dragged down after US President Donald Trump hinted at new tariffs on Chinese imports. (Xinhua/Reuters)
