Hong Kong's benchmark index posted its biggest daily gain in more than a month on Monday, as pro-democracy activists scaled down protests and upbeat U.S. jobs data provided some relief over the outlook for the global economy.

In Hong Kong, protesters allowed civil servants to pass through barricades unimpeded, on their way to work at the main government offices. Some banks reopened branches that they had closed during the mass protests over the past week.

The Hang Seng Index finished up 1.1 percent at 23,315.04 points, the best one-day gain since Sept. 3. The China Enterprises Index of leading offshore Chinese listings in Hong Kong added 0.6 percent.

Macau casinos rallied as investors bet on a technical rebound in the oversold sector, despite data released at midday showing gambling revenue in the world's biggest gambling hub declined for a fourth consecutive month.

Sands China soared 7.1 percent, while Galaxy Entertainment Group jumped 6.6 percent. Both hit their lowest level in more than 13 months on Friday.

Index heavyweights, laid low by across the board selling last week, posted solid gains on Monday. Tencent Holdings climbed 3.2 percent and HSBC Holdings rose 0.6 percent.
