Did Macao punish AmCham leaders for U.S. laws on Hong Kong?

From the editorial board of the South China Morning Post, which generally has an approach that is highly sympathetic to Beijing:

The Hong Kong human rights law passed recently by the United States Congress is fraught with potential for unintended consequences. Ironically, one has already rebounded on the American Chamber of Commerce in Hong Kong.

Macau authorities inexplicably denied entry to AmChamโ€™s president and chairman to attend the chamberโ€™s Macau annual ball at the weekend. Macauโ€™s security minister has dismissed any connection with the U.S. legislation, insisting that โ€œsafety risks and threatsโ€ were the only considerations in such decisions. However, the exclusion resonates with Beijingโ€™s warning of possible retribution for the Hong Kong law.
