How Vietnam’s New Personal Data Protection Law Reshapes Market Research Workflows

Vietnam is an early mover on data localization, and that reality is already shaping how market research is executed. Under Decree No. 53/2022/ND-CP (2022), which elaborates on Vietnam’s 2018 Law on Cybersecurity, foreign entities providing a wide range of services can be mandated to store specific user data in Vietnam and establish an office in the country. For market research teams, that means a simple “collect globally, process centrally” model can be harder to justify. The workflow must anticipate where respondent and user data is stored, which systems touch it, and whether the fieldwork stack includes foreign service providers that may be asked to localize data and maintain a local presence.

Cross-border operations also become more procedural. Vietnam is described as having high, broad localization expectations: foreign service providers (including telecoms, online services, and e-commerce) may be requested to store user data locally and may also need a local office or branch. Offshore transfers of personal data, important data, and core data can be subject to Ministry of Public Security notification or approval, and must satisfy consent, necessity, and safe handling requirements. In practical workflow terms, research teams should treat “transfer readiness” as a project phase. That phase includes mapping whether a study requires offshore transfer, designing consent language for the purpose and route of processing, and documenting why the transfer is necessary for the study.

Workflow Changes That Matter Most for Research Teams

Expect vendor management and architecture choices to move from procurement details to core methodology. If a research program uses offshore analytics, global panel partners, or centralized customer-data environments, teams may need to redesign flows so certain datasets stay in Vietnam, or so processing happens through locally established entities. A localization-first approach also affects how quickly insights can be delivered, because the “right to move data” can become conditional. This is where the Vietnam Personal Data Protection Law market research conversation becomes operational: it is about building repeatable checklists for consent capture, defining what is processed locally versus offshore, and ensuring the organization can show “safe handling” in each step rather than assuming it.

It also helps to compare how other jurisdictions are modernizing privacy rules, because global research teams rarely work in only one market. The U.K.’s Data (Use and Access) Act (DUAA) reforms the U.K. GDPR, the Data Protection Act, and PECR, and is framed around easier sharing of business and customer data, plus a digital identity verification system. In the EU, the GDPR has been in effect since 2018, and discussion has included potential reviews to scale back some rules. This contrast matters for governance: a multinational insight function may face “easier sharing” expectations in one market while working under strict localization and transfer gates in Vietnam, so a single global workflow template can break unless it is modular by country.

Finally, organizations should not treat privacy workflow work as separate from commercial reality. Vietnam is home to fast-scaling enterprises with detailed financial targets in public reporting. For example, Vingroup reported 2025 net revenue of nearly VND331.84 trillion ($12.6 billion), up 75.5% year on year, while net profit rose 109.7% to nearly VND11.07 trillion ($420.05 million), and it is targeting 2026 net revenue of VND450 trillion ($17.08 billion) and net profit of around VND25 trillion ($949 million). For researchers supporting such growth agendas, faster cycles and broader data use can be business priorities. Strong workflows are the bridge: they let teams run compliant sampling, storage, and transfer processes without stopping strategic decision-making when governance questions arise.
