After a protracted period of deliberation, the Vietnamese government ultimately passed the country’s “historic,” first-ever Personal Data Protection Decree (“PDPD”) on April 17, 2023, as Decree No. 13/2023/ND-CP.

Accordingly, sensitive personal data comprises, among other things, political and religious views, health status and private life information as recorded in medical records,
