The Macau government is considering legislation that would provide for the mandatory closure of casinos in the event of public emergencies, Inside Asian Gaming reported.

This comes after last weekend’s closures as Typhoon Mangkhut hit the special administrative region, already leading to downward revenue projections for the month. The government finally allowed the casinos to reopen Monday morning, after over 24 hours.

Macau Secretary for Economy and Finance Lionel Leong said the government has yet to decide whether required closures would be part of the ongoing discussions on changes to Macau’s civil protection system.

“Will the closure in the future be regular? For the time being, I still cannot say,” Leong said, noting that the SAR’s six casino operators had fully cooperated with the directive to close the casinos, but that the procedure during similar events could be optimized.
