The Hang Seng Index rose 316.07 points, or 1.38 percent, to open at 23,183.81 points on Monday.

The rally follows signs of a de-escalation in the Sino-US trade dispute after talks in Geneva at the weekend between Chinese and US delegations.

Meanwhile, in a statement filed with the Hong Kong Stock Exchange on Monday, mainland EV battery giant CATL said it aims to raise about HK$31 billion in its Hong Kong listing scheduled for May 20. It will be the largest IPO this year.
