The decision by Ireland\u2019s privacy regulator to take on Twitter marks an important moment in the history of the EU\u2019s landmark GDPR privacy legislation, with the matter now in the hands of other European privacy watchdogs for their input. The case is significant because it tells us as much about how such investigations will be managed in the future as it does about Twitter\u2019s alleged privacy breach. Meanwhile, China\u2019s top legislative and advisory bodies have renewed calls for greater privacy safeguards, just as Beijing is considering two pieces of legislation designed to achieve just that.
