Casino operators in Macau are looking for ways to keep the ball rolling in the world’s biggest gambling hub amid as Beijing authorities continue to push for diversification.

For Francis Lui, deputy chairman of Galaxy Entertainment Group, the answer to boost the gambling enclave’s tourism numbers lies on an island—Hengqin.

A pet project of Chinese President Xi Jinping, the 100-square kilometer island is supposed to help expand Macau’s appeal as a tourist destination, among other things. Hengqin already has a theme park, but visitors between the two islands need to pass immigration checkpoints before they can travel back and forth.

But the idea of relaxing border controls between Macau and next-door neighbour Hengqin may just be the key to boost the two islands’ tourism, according to Lui.
