As Chinese President Xi Jinping arrives in Macau this weekend for his first official visit in five years, the message from Beijing is clear: the world's biggest gambling centre cannot remain a one-industry town.
Xi's pervasive anti-graft campaign contributed to a disastrous year for major casino companies, which have lost a combined US$58 billion (S$76 billion) in market value over the past six months as VIPs stayed away.
The former Portuguese colony became a paradise for Chinese government officials and rich businessmen to flaunt their wealth and indulge themselves with private jets and sumptuous hotel suites. Gambling revenue hit US$45 billion last year, seven times Las Vegas's take.
But it also became a pathway for extracting money from China - something the government is targeting aggressively.
China extended a crackdown on illicit money transfers into Macau, giving its Economic Crimes Investigation Bureau access to transactions made through the state-backed UnionPay credit card, the South China Morning Post reported on Wednesday.
The move, timed just ahead of Xi's high-profile visit, is the latest in a string of actions aimed at curbing illicit funds leaving the country, a priority for Xi as he goes after corrupt officials who have fled overseas.
UnionPay has been a conduit for growing numbers of Chinese to illegally send billions of dollars abroad, a Reuters special report showed in March.
The corruption link helps explain Beijing's interest in seeing Macau expand beyond casinos into more family-friendly entertainment.
Li Gang, China's representative in Macau, warned on Sunday that "the dominance of one industry can lead the city to prosperity, but it also can lead to its demise".
Gambling merited barely a mention in an editorial this week in the Communist Party's official newspaper, the People's Daily, praising Macau as a platform for international trade and a world heritage site.
Junket operators who lend money to wealthy mainland Chinese gamblers said they would keep a low profile during Xi's visit, which marks the 15th anniversary of Macau's handover from Portugal. He is expected to voice his support for Macau diversifying beyond gambling.
"Xi's visit definitely means more control on the gaming path, especially for VIPs," said one junket operator who declined to be named, referring to the high-rollers who accounted for two-thirds of Macau's revenue last year but now represent just 56 percent.
Hong Kong-listed casino stocks have plunged 32-51 percent since the start of the year, widely underperforming the benchmark Hang Seng Index, which has dropped 2 percent in the same period.
