And Australia has the social media ban, Brazil has an age verification requirement, and Canada has a bill in process -- see @Paulatics's speech at https://mstdn.ca/@Paulatics/116410495484238161
In terms of coordinating the efforts interenationally, there are several focal points
the Age Verification Providers Association does a lot of lobbying (because it's a big money-maker for their companies)
the surveillance-industrial complex is international; age verification companies like Persona pass information to Palantir and everybody else as part of verifying ages, and even though age verification advocates claim the laws prohibit the data from being used for anything else ... they're lying. (I picked Persona and Palantir because they're both Peter Thiel companies but they're not the only ones -- data brokers have age verification services, Sam Altman's got an identity verification company etc.)
anti-LGBTQ+ bigots and fascists work together across borders.
so do child safety advocates -- some of whom are front organizations for one or more of the above, but many of whom legitimately do want to protect kids.
