Vietnam-specific requirements to plan for

Projects for businesses in Hanoi have to work for local customers and local rules. These points are planned from the first milestone:

  • Vietnamese diacritics need full font support for readability and SEO.
  • Personal Data Protection Law (No. 91/2025/QH15) and Decree 356/2025, both effective 1 January 2026: Consent and impact assessments are required, and some cross-border transfers must be documented.
  • Interface and content languages: Vietnamese and English.
