China should do the same on other Chinese criminal-operated gambling establishments in Myanmar and Thailand too.

This seems like something that would be effectively enforced by applying state pressure to payment networks. I know some banks just deny any transaction coded as gambling, although that could be personal moralization or chargeback risk fears, as well as actual legal rules.

If there’s some fraud factor involved (I recall at one point seeing some scheme in the US where people would buy wildly overpriced items from a “seller” where the $500 golf balls were really a $500 deposit to a betting platform) you might not even need new rules to intervene.

Hell, you could weaponize the players: if there’s a bounty on firms and people that middleman the money, you incentivize anyone who lost money to help the state slash the operators’ tentacles.

Can’t imagine the business staying afloat if they had to resort to players mailing wads of physical hundred-yuan notes to a purser every time they needed to replenish their account.
