There is not a single comprehensive data protection law in Vietnam. Instead, regulations on data protection and privacy can be found in various legal instruments. The right of privacy and right of reputation, dignity and honour and fundamental principles of such rights are currently provided for in Constitution 2013 (“Constitution”) and Civil Code 2015 (“Civil Code”) as inviolable and protected by law.

Regarding personal information, the key principles on collection, storage, use, process, disclosure or transfer of personal information are specified in the following main laws and guiding documents, among others:

  • Criminal Code No. 100/2015/QH13, passed by the National Assembly on 27 November 2015; as amended from time to time (“Criminal Code”);

  • Law No. 51/2005/QH11 on E-transactions, passed by the National Assembly on 29 November 2005 (“E-transactions Law”);
  • Decree No. 53/2022/ND-CP of the Government dated 15 August 2022 elaborating a number of articles of the Law on Cybersecurity of Vietnam (“Decree 53”);
  • Decree No. 85/2016/ND-CP dated 1 July 2016, on the security of information systems by classification (“Decree 85”);
  • Decree No. 72/2013/ND-CP dated 15 July 2013 of the Government, on management, provision and use of Internet services and online information; as amended by Decree No. 27/2018/ND-CP dated 1 March 2018 and Decree No.150/2018/ND-CP dated 7 November 2018 (“Decree 72”);

  • Decision No. 05/2017/QD-TTg of the Prime Minister dated 16 March 2017 on emergency response plans to ensure national cyber-information security (“Decision 05”); and
  • Resolution No. 27/NQ-CP of the Government dated 7 March 2022 approving the Draft Personal Data Protection Decree (“Resolution 27”).

Each aspect and each industry may have their respective regulating documents. In other words, applicability of legal documents will depend on the factual context of each case, e.g. businesses in the banking and finance, education, healthcare sectors may be subject to specialized data protection regulations, not to mention to regulations on employees’ personal information as provided in Labour Code 2019 (“Labour Code”).

The most important Vietnamese legal documents regulating data protection are the Cybersecurity Law and Network Information Security Law. However, it is worth noting that, unlike cybersecurity laws in other jurisdictions that were inspired by the GDPR of the EU, the Cybersecurity Law of Vietnam shares similarities with China’s Cybersecurity Law enacted in 2017. Such law focuses on providing the government with the ability to control the flow of information; meanwhile, the Network Information Security Law enforces data privacy rights for individual data subjects.

Most recently, the Government issues Decree 53 which elaborates a number of articles of the Cybersecurity Law and started to take effect from 1 October 2022. Notably, Decree 53 sets out the requirements relating to data localization and the establishment of branches / representative offices of foreign service providers, which will be discussed further below. Furthermore, a draft Decree detailing a number of articles of the Cybersecurity Law (“Draft Cybersecurity Decree”), notably including implementation guidelines for data localization requirements, together with a draft Decree detailing the order of and procedures for the application of administrative sanctions against cybersecurity related violations and a draft Decision of the Prime Minister promulgating a List of information systems important for national security, are being prepared by the Ministry of Public Security (“MPS”) in coordination with other relevant ministries, ministerial-level agencies and bodies.

In addition, the MPS has been working on a Draft Decree on Personal Data Protection (“Draft PDPD”), which is contemplated to consolidate all data protection laws and regulations into one comprehensive data protection law as well as make significant additions and improvements to the existing regulations. The Draft PDPD was released for public comments in February 2021 and was originally scheduled to take effect by December 2021. However, due to the extreme sensitivity of the issues intended to be regulated by the Draft PDPD (including the data localization requirement and regulatory approval for sensitive data processing), the Draft PDPD received immense negative comments from the public and foreign governments. Thus, its finalization process has taken much longer than the MPS first anticipated. That being said, the Draft PDPD has just moved one step closer to its final promulgation, given the Government’s issuance of Resolution No. 27/NQ-CP dated 7 March 2022 (“Resolution 27”). More specifically, Resolution 27 clearly indicates the Government’s approval of the promulgation of the latest version of the Draft PDPD. In addition, it seems that the Draft PDPD is now under the review of the National Assembly’s Standing Committee already as per the procedures instructed and timeline requested under Resolution 27.

Definition of personal data

There is no single, pervasive definition of personal data in Vietnam, but the concept of personal information, definition thereof and its variations can be found in the various laws, regulations and guidance that comprise the data protection framework in Vietnam. In summary, personal information is generally defined as information associated with the identification of a specific person, e.g. full names, date of birth, profession, title, contact addresses, email addresses, telephone numbers, ID numbers, passport numbers.

Definition of sensitive personal data

Currently, there is no particular definition of ‘sensitive personal data’ specified in the laws of Vietnam, except for highly controlled industries such as banking and finance.

However, under the Draft PDPD, ‘personal data’ is proposed to be defined as data about individuals or relating to the identification or ability to identify a particular individual. Personal data would be categorized into two groups: (a) basic personal data, and (b) sensitive personal data:

  • Basic personal data is defined to include: (i) surname, middle name, birth name, alias (if any); (ii) date of birth; (iii) date of death or date of going missing; (iv) blood type and gender; (v) place of birth, place of birth registration, permanent residence, current residence, hometown, contact address, email address; (vi) education; (vii) ethnicity; (viii) nationality; (ix) phone number; (x) ID card number, passport number, citizen identification number, driver's license number, plate number, personal tax identification number, social insurance number; (xi) marital status; and (xii) data reflecting online activities or activity history.

  • Sensitive personal data is defined to include: (i) personal data on political and religious views; (ii) personal health data, i.e. information related to the physical or mental health status of the data subject collected and identified during the process of registration or provision of medical services; (iii) personal genetic data, i.e. information relating to inherited or acquired genetic characteristics of each individual; (iv) personal biometric data, i.e. information about physical and biological characteristics of each individual; (v) personal data on gender status, i.e. information about people identified as male, female, gender neutral, androgynous, or having both masculine and feminine characteristics or self-identifying a different gender from the gender identified at birth; (vi) personal data about life and sexual orientation; (vii) personal data about criminals and criminal acts collected and stored by law enforcement agencies; (viii) personal financial data, i.e. information used to identify an account, card or payment instrument provided by a financial institution to a data subject or information about the relationship between a financial institution, original financial data and data subjects, including records, financial status, credit history, and income level; (ix) personal location data, i.e. information about the individual's previous and current physical location; (x) personal data about social relationships; and (xi) other personal data as specified by law to be special and subject to confidentiality protection.

Vietnam does not have a single national data protection authority. Instead, the authority on State management of certain aspects of information and / or data protection has been given to a number of competent State authorities. To some extent, the key State competent authorities in charge of information and / or data protection would be the Ministry of Information and Communications (“MIC”), the MPS and the Vietnam Cybersecurity Emergency Response Teams / Coordination Center (“VNCERT/CC”) directly managed by the Authority of Information Security (“AIS”) under the MIC. Their key roles are particularly as follows:

  • MIC, particularly the AIS shall be responsible for management of the provision of cyberspace services (e.g. social network, gaming online, e-commerce, etc.), such as requesting cyberspace service providers to delete illegal data uploaded on their system / network;
  • MPS, particularly Department for Cybersecurity and High-tech Crime Prevention and Fighting (“A05”),  is responsible for supervision of national cybersecurity, e.g. to request cyberspace service providers to (i) store data and establish branches or representative offices in Vietnam (if applicable) and (ii) provide users’ information for serving investigation into cybersecurity crime;
  • VNCERT/CC acts as the National Coordination Center for response to cybersecurity incidents and information security testing.

In addition to the above, subject to each specific industry (e.g. banking and finance; education; healthcare; natural resources and environment; culture, sports and tourism; etc.), the State management authority in charge of such industry and its IT center shall be involved in relevant information system protection.

Moreover, under the upcoming Draft PDPD, there will soon be another authority which is directly in charge of data protection matters, namely the Personal Data Protection Committee (“PDPC”). Pursuant to the Draft PDPD, the PDPC is expected to have a number of functions and duties, most notably:

  • Receiving certain complaints against violations by data processors and requesting the MPS to settle such complaints;
  • Requesting a unit of the MPS to inspect the data protection activities of a processor and acting as the inspection team;
  • Evaluating and rating processors’ personal data protection reliability with its own established criteria and publish the result on the National Personal Data Protection Portal operated by the PDPC; and
  • Operating the registration system for sensitive data processing, and cross-border, etc.

There is no requirement under current Vietnamese laws whereby such data controller of private sector is required to have it or its activities registered with the local authorities (e.g. MPS, MIC or VNCERT/CC), except in cases where:

  • Foreign enterprises which provide services on telecom networks and on the Internet and other value-added services in cyberspace in Vietnam (“cyberspace service providers”) may need to have branches or representative offices in Vietnam (subject to specific guidance of the Government under Decree 53);
  • Where organizations or individuals involved in cross-border public information provision activities rent digital information storage facilities within the territory of Vietnam so as to provide their services or are reported to provide public information to be used or accessed by at least 1 (one) million Internet users in Vietnam a month, they shall have the obligation to send a written notice to the MIC via post or email (to the email address [email protected]), informing the MIC of the following information:
    • In the case of an organization, registered name, transactional name, and name of the licensing country are required; in the case of an individual, name of such individual is required;
    • Main office address of an organization, permanent residence address and nationality of an individual owning an electronic information page and location of the main server system;
    • Principal contact agent of an overseas organization or individual and principal contact agent operated within the territory of Vietnam, including the following information such as name of an organization, individual, contact email address and telephone number.

Moreover, the current Draft PDPD requires that an organization wishing to collect or process sensitive personal data (hereinafter referred to as “sensitive data processor”) registers such processing activities with the PDPC prior to the collection and processing. A sensitive data processor must prepare and submit an impact assessment report addressing the potential harm to data subjects due to the proposed processing, as well as the measures to manage, minimize, or eliminate such harm. The PDPC will process the applications within 20 working days from the date of receipt of a valid application, which means the date that all information and documents provided in the application are acceptable to the officers in charge.

Similarly, the Draft PDPD also requires data transferors to obtain prior approval from the PDPC before transferring Vietnamese citizens’ personal data out of Vietnam. In addition, they must also: (i) obtain prior consent from the data subjects; (ii) store the original data in Vietnam; and (iii) secure proof that the recipient country has personal data protection regulations and practices at a level equal to or higher than the level specified in the Draft PDPD.

Data Protection Officers

Under the current laws of Vietnam there is no regulation mandating a typical company to appoint a Data Protection Officer (“DPO”). However, certain types of organizations (e.g. big information system owners and others such as telecoms enterprises, banks, State bodies, information system owners using State budgets, etc.) are required to appoint specialized information security focal points and contact persons to supervise and warn relevant parties on cyber-information security incidents, etc. These officers are expected to be in charge of cybersecurity incidents rather than data protection issues. Other strict requirements (under various legal documents) are also applicable to such kinds of organizations which do not cover “companies of the private sector”.

However, the foregoing position may be changed in the near future as the draft PDPD specifically requires a data controller to appoint a DPO and notify such DPO’s contact information to the PDPC.

Collection & Processing

According to Vietnamese laws, the solid legal basis for the processing of personal information (that means the performance of one or some acts of collecting, editing, utilizing, storing, providing, sharing or spreading personal information in cyberspace for commercial purpose) is a prior explicit consent given by the data subject. Specifically, it requires that organizations that process personal information shall collect personal information only after (i) having notified data subjects of the scope, purpose, storage period, form and location of collection, storage, processing, use, disclosure and transfer of such information (the relevant terminologies cover “collect, store, process, use, disclose and transfer” rather than just “collection and processing” of data); and (ii) obtaining their consents before. The traders or organizations collecting and using the consumers’ personal information on E-commerce website must set up the mechanism for the consumers / subjects to clearly express their consent through online functions on the website, e-mail, messages or other methods as agreed by the two parties.

In addition, consent under the Draft PDPD is clearly set out to exclude implied consent (i.e. silence or non-response from data subjects). More specifically, the form of consent is stipulated under the Draft PDPD as follows:

  • Silence or non-response of data subjects (implied consent) shall not be interpreted as consent;
  • Data subjects’ consent must be in a format that can be printed or copied in writing; and
  • With regard to processing sensitive personal data, the data subjects must be informed that the data to be processed is sensitive personal data and their consent must be obtained in a format that can be printed or copied in writing.

However, based on the specific purpose for processing of personal information, the laws also provide an alternative legal basis besides consent. Particularly, organizations may collect, process, use, store, disclose and transfer personal information of other people without the consent when that information is used for the following purposes:

  • Signing, modifying or performing contracts on the use of information, products or services in the network environment (generally defined as “the environment in which information is provided, transmitted, collected, processed and exchanged via information infrastructure");
  • Calculating charges for use of information, products or services in the network environment; and
  • Performing other obligations provided for by law (e.g. at request of competent authority as prescribed in the law of Vietnam).

In addition, the traders and organizations collecting and using consumers’ personal information on E-commerce websites shall not need the consumers / subjects’ prior consent in the following cases:

  • Collecting personal information that has been publicized on E-commerce websites;
  • Collecting personal information to sign or perform contract of sale and purchase of goods and services;
  • Collecting personal information to calculate the price and charge of use of information, products and services on the
  • network environment;
  • Collection of personal information for performing other obligations in accordance with the law.

Under the Draft PDPD, personal data may be processed without data subjects’ consent in the following cases:

  • As required by the law;
  • In support of national security, social order and safety;
  • As required by the law in emergency events that threaten life or seriously affect the health of the data subject or the public health;
  • In support of investigation and handling of regulatory violations;
  • In compliance with specific provisions that explicitly allow the processing of personal data without the data subject's consent under international agreements or treaties to which Vietnam is a signatory; and
  • Process personal data for research or statistics purposes.

Moreover, Resolution 27 also provides five cases in which personal data processing without data subjects’ consent is allowed. In particular:

  • The data processing is essential to cope with emergency situations that threaten the life, health, or safety of data subjects or other individuals. The data controller, data processor, data controller and processor, third parties must be responsible for proving this.
  • The disclosure of person data is permitted by law.
  • The data processing is essential for matters of national security, national defense, and is done by authorized agencies in accordance with other laws.
  • Authorized state units use the personal data to investigate and handle a law violation case in accordance with the law.
  • The personal data are processed by authorized state agencies to serve the operation of state agencies as provided by law.

Especially, the data controller is required to:

  • Process the collected data strictly in accordance with the scope and purpose notified to the data subjects when obtaining their consent. In case of any change to the scope and purpose of data processing, the data controller shall promptly notify the data subject before such changes;
  • Provide the data subject with their personal information collected and stored by the data controller upon receipt of a request from the data subject;
  • Immediately comply with the request and notify such data subject or grant him / her the right to access information or to do so upon receipt of a request from the data subject for re-examination, update, correction, modification or cancellation, or for the stoppage of the provision of personal information to a third party, and not supply or use relevant personal information until such information is corrected;
  • Take necessary measures to protect personal information, and notify the data subject if the data controller fails to comply with its / his / her request for technical or other reasons; and
  • Delete the stored personal information when they have accomplished their use purposes or the storage time has expired and notify the data subject thereof, unless otherwise prescribed by law.

In general, if a data controller wishes to share, disclose or otherwise transfer an individual’s personal information to a third party (including group companies), the data controller they must inform the data subjects and obtain prior explicit consent from such data subjects. In particular, the traders or organizations collecting and using the consumer’s personal information on an E-commerce website must have specific mechanisms for the information subjects may choose the permission or refusal of using their personal information in the cases of using personal information to send advertisements and introduce products and other commercial information.

In cases of cross-border transfers, the data exporter / importer currently does not need to obtain authorization from or make a filing with the Vietnamese regulators, or notify the supervisory authority before carrying out any automatic processing operation or set of such operations, including a transfer of personal information from Vietnam to a foreign country or an international organization. There are exceptions for the transfer of information that is classified as being a State secret.

That being said, it is important to note that cross-border transfer of personal data out of Vietnam will soon be subject to a lot of stringent conditions under the Draft PDPD. In fact, the Draft PDPD provides that the following four conditions must be fulfilled before personal data of Vietnamese individuals can be transferred out of Vietnam (as mentioned above):

  • Consent must be obtained from the data subjects;
  • The original data (i.e. the initial personal information collected and processed by the data controller without transferring to any third party) must be stored in Vietnam;
  • The data controller must have proof that the recipient country has personal information protection at a level equal to or higher than the level specified in the Draft PDPD; and
  • A written approval for transfer must be obtained from the PDPC.

According to the latest available version of the Draft PDPD, the application dossier for cross-border transfer of personal data consists of:

  • An application for cross-border transfer of personal data, which consists of: name, registry, place of business, residence and other contact information of the Data Processor; cited legal basis for cross-border transfer of personal data; purpose of cross-border transfer of personal data; types of personal data to be transferred abroad; sources of personal data registered for cross-border transfer; location where cross-border transfer of personal data is registered; conditions for cross-border transfer of personal data; a detailed description of measures to protect personal data;
  • An impact assessment report for cross-border transfer of personal data, which consists of a detailed description of the cross-border transfer of personal data, purpose of transferring personal data abroad; assessment of potential harm; measures to manage, minimize or eliminate such harm; and
  • If the personal data to be transferred overseas includes sensitive personal data, documents related to the contents mentioned in the application for processing sensitive personal data and the impact assessment report for processing sensitive personal data.

The Draft PDPD in fact provides an exemption to the foregoing cross-border data transfer requirements when there is: (a) consent from the data subject; (b) approval from the PDPC; (c) commitment from the data controller to protect the data; and (d) commitment from the data controller to apply measures to protect the data. However, the Draft PDPD does not elaborate on the specific types of protection measures which need to be applied by the data controller. In addition, it is unclear if one or all four of the above-mentioned conditions should be met. That being said, it is widely believed that the Draft PDPD has been significantly amended to provide more relaxation on these cross-border data transfer requirements. Accordingly, the requirements to store original data in Vietnam and to obtain prior approval from the PDPC might be removed and replaced with, among other things, the obligation of having in place a legally binding agreement between the data exporter and data importer. However, at the moment, the most updated version of the Draft PDPD which might include such relaxed provision is strictly confidential and has not been revealed to the public yet.

In addition to the above requirements, it is worth noting that data localization is an increasing trend in Vietnam, which is provided in certain legal documents, e.g.:

  • According to Circular 24, electronic general information pages and social networks as entities licensed in Vietnam must use at least one domain name “.vn” and store information in servers identified by IP addresses in Vietnam.
  • The Cybersecurity Law requires that domestic or foreign cyberspace service providers carrying out activities of collecting, exploiting / using, analysing and processing data being personal information, data about service users' relationships and data generated by service users in Vietnam must store such data in Vietnam for a specified period to be stipulated by the Government. In particular, according to Article 26 of the Decree 53, domestic and foreign enterprises providing telecoms and online services to customers in Vietnam may be required to locally store certain customer-related data in Vietnam for a certain period prescribed by law if the authority alerts them that their services/online platforms have been used to commit violations of Vietnam’s laws but such online service providers fail to remedy the situation upon the request of the authority. According to the latest version of the Decree 53, while all domestic organizations providing telecoms services and online services to customers in Vietnam would be required to store their customer data in Vietnam, the foreign organizations which could be subject to the foregoing data localization requirements only include those engaging in the following 10 services: (i) telecommunications; (ii) data storage and sharing in cyberspace; (iii) supply of national or international domains to service users in Vietnam; (iv) E-commerce; (v) online payment; (vi) intermediary payment; (vii) transport connection via cyberspace; (viii) social networking and social media; (ix) online electronic games; and (x) providing, managing or operating other information in cyberspace in the form of messages, phone calls, video calls, email or online chats. Pursuant to Decree 53, only the following types of data is required to be stored in Vietnam:
    • Data on personal information of service users: i.e., data on information in the form of symbols, letters, numbers, images, sounds, or equivalent to identify an individual (“Personal Data”);
    • Data created by service users in Vietnam: i.e., data on information in the form of symbols, letters, numbers, images, sounds, or equivalent reflecting the process of participating, operating, and using cyberspace of service users and information on devices and network services used for connection with cyberspace in the territory of the Socialist Republic of Vietnam. It should be noted that the information under this category of data which is required to be stored in Vietnam only includes information on service account name, service usage time, credit card information, email address, IP addresses for the latest login and logout, registered phone number associated with account or data (“Account Data”); and
    • Data on the relationships of service users: i.e., data on information in the form of symbols, letters, numbers, images, sounds, or equivalences reflecting and identifying relationships of service users with other people in cyberspace. Decree 53 further specifies that the information under this category of data which is required to be stored in Vietnam only includes information on friends and groups with which the service user connects or interacts in cyberspace (“Relationship Data”).

Moreover, foreign enterprises engaging in the abovementioned services are also required to establish branches or representative offices in Vietnam in case the authority alerts them that their services/online platforms have been used to commit violations of Vietnam’s laws but failed to remedy upon the request of the authority. The time for such establishment shall commence when the enterprises receive the request to do so until such enterprises terminate their operation in Vietnam or the prescribed services are no longer available in Vietnam.

Organizations must take necessary managerial or technical measures to ensure that the personal information shall not be lost, stolen, disclosed, modified or destroyed. Remedial measures must be taken immediately if personal information is being or is likely to be disclosed or destroyed.

Indeed, generally, the data controller shall classify information based on its secrecy in order to take appropriate protection measures; and agencies and organizations that use classified and unclassified information in activities within their fields have to develop regulations and procedures for processing information, and determine contents and methods of recording authorized accesses to classified information, in which:

  • Personal information protection policies to be developed and published by traders and organizations collecting and using the consumers’ personal information on E-commerce websites must provide the purpose of collection; scope of use; storage period; organizations and persons authorized to access to such personal information; address of data controller, including way of contact for the consumers to ask about the collection and processing information related to them; methods and tools for data subjects to access and modify their personal information on the E-commerce system of the data controller;
  • The above contents must be clearly displayed for the consumers before or at the time of information collecting. The language is Vietnamese. The contents are clear and understandable. The font size of the text is at least 12. The paper background and ink colour used in the terms must contrast;
  • If the information collection is done through E-commerce website of the data controller, the personal information protection policies must be made ​​public in a conspicuous place on the website; and
  • The traders, organizations or individuals that own E-commerce websites with online payment functions must publish on their website policies on security of customer’s payment information.

Breach Notification

The laws of Vietnam introduced a general requirement for the reporting and notification of actual or suspected personal information security incidents. A data breach reporting / notification requirement in Vietnam will be triggered if the data incident falls within any of the following criteria:

Criterion 1. The affected data system is located in Vietnam.

Criterion 2. The services provided to customers in Vietnam fall under the categories of Regulated Services, including (1) telecommunication services; (2) data storage and sharing in cyberspace; (3) services providing national or international domain names to service users in Vietnam; (4) e-commerce; (5) online payment; (6) payment intermediary; (7) connecting transportation in cyberspace; (8) social networks and social media; (9) online games; and (10) other services that provide, manage and operate information in cyberspace in the form of messages, voice calls, video calls, email, or online chatting.

Criterion 3. The incident causes “significant loss” to the legitimate rights and interests of the affected Vietnamese persons.

Where there is a data security incident, organizations must promptly take relevant measures to mitigate and notify relevant data subjects and / or relevant competent State authorities, as the case may be, in a timely manner, e.g. 5 days after detection of the security incident, and must provide an update on the incident status when it is completely resolved, Affected organizations and individuals must be notified of the data incident if the incidents fall under Criterion 2 or Criterion 3.

In the case of an incident under Criteria 1 that is beyond the control of the organization, the operator of the information system must immediately prepare an initial report on the incident to report such incident to the relevant agencies and a final report on response to the incident within five days after finishing responding to the incident. Moreover, if the information system of a trader, organization or individual engaged in e-commerce is attacked causing risk of loss of consumer’s information, the data controller must notify the authorities within 24 hours after the detection of incident.

Normally, the data controller would be required to give relevant notifications to the following State authorities:

  • Local police agency (i.e. Police Department of Cybersecurity and High-Tech Crime Prevention and Fighting under the MPS with regard to offshore service providers, provincial police department where the head office of data controller is located); and

  • VNCERT/CC directly managed by the AIS under the MIC.

Subject to specific data protection laws and the regulations breached, the sanctions in relation to data protection breaches are scattered across various different laws and regulations. In general, amongst others, the major type of sanction would be administrative penalty. For example, failure to obtain prior consent of the data subjects on collection, processing and use of their information shall be subject to a monetary fine varying from VND 10 million to VND 20 million. In serious cases, according to the Criminal Code, any person who commits illegal use of information on the computer or telecommunications network may be liable to a monetary fine varying from VND 30 million to VND 1 billion or face a penalty of up to 3 years’ community sentence or 6 months – 7 years’ imprisonment; and the offender might also be liable to a monetary fine varying from VND 20 million to VND 200 million or prohibited from holding certain positions or doing certain jobs for 1 – 5 years.

In addition, as mentioned above, the MPS is also working on the Draft Decree on administrative sanction in cybersecurity field (“Draft Sanction Decree”) to provide a clear legal basis regarding the appropriate monetary fines as well as other additional sanction measures / remedy measures which are applicable to the infringement in cybersecurity and data protection. In coherence with the Draft PDPD, the Draft Sanction Decree regulates a fine of up to 5% of the revenues earned in Vietnam in case of repetition (for 3rd times and above) of violations related to: (i) cross-border data transfer; (ii) protection of personal data in the business of marketing services, introducing advertising products; (iii) prevention and protection of sale and purchase of personal data; (iv) responsibility to protect personal data); and (v) ensuring information security. It is worth noting that the Draft Sanction Decree is also expected to be passed very soon.

Electronic Marketing

According to Vietnam’s new anti-spam regulation (i.e. Decree No. 91/2020/ND-CP on anti-spam text messages, emails and calls), advertisements by text message, email and call may only be sent or made in compliance with specific requirements, notably including:

  • it is prohibited to send advertising messages or make advertising calls to phone numbers on the Do-Not-Call Register;
  • for phone numbers not included in the Do-Not-Call Register, only one initial advertising registration message (i.e. a message inquiring whether the user would like to receive advertising communications from the advertiser) is allowed;
  • if the user refuses to receive advertising messages after receiving the initial advertising registration message, no further advertising message is allowed;
  • immediately after receiving a refusal request from a user, the advertiser must terminate providing advertising messages, email or calls to such user;
  • no more than three advertising messages / three advertising emails / one advertising call per day may be sent or made to the same user;
  • advertising messages are only allowed from 7 a.m. to 10 p.m.; advertising calls are only allowed from 8 a.m. to 5 p.m.; and
  • advertising contents must comply with advertising laws.

Once again, the traders or organizations collecting and using the consumers’ personal information on E-commerce websites must have a specific mechanism for the information subjects to choose the permission or refusal of using their personal information in the cases of using personal information to send advertisements and introduce products and other commercial information.

Additionally, the organization shall not be allowed to hide their names or use unlawfully the name of others when sending advertisements via e-mail or text message. Specific information must be stated in each electronic message: for example,  information about the advertiser and the advertising service provider, opt-out function (refusing acceptance of advertisements), and a label identifying “QC” or “ADV” [QC means Adv. in Vietnamese].

With regard to the method of advertising into Vietnam (i.e. to target Vietnam-based recipients), foreign organizations which do not operate in Vietnam (i.e. do not have commercial presence in Vietnam) but wish to advertise their products, goods, services and operation in Vietnam, are required to hire a Vietnam-based advertising service provider (a company with business lines of provision of advertisement) to conduct relevant advertising activities.
