Prohibited investment sectors are a crucial consideration for foreign investors (FDI) when entering the Vietnamese market. Understanding which sectors are restricted or completely prohibited not only helps investors avoid legal risks but also ensures effective, safe, and lawful investments. The following article will provide the most detailed information on prohibited investment sectors, particularly concerning foreign investors in Vietnam, according to the latest legal regulations.

1. What are prohibited investment sectors?
Definition of Prohibited Investment Sectors
Prohibited investment sectors are areas of business activity that Vietnamese law prohibits any organization or individual from participating in, due to reasons related to national security, public order, social ethics, and human health. This regulation applies to both domestic and foreign investors. It is one of the key aspects that investors must clearly understand before initiating any investment projects in Vietnam to avoid serious legal risks.
Purpose of Prohibiting Investments
The prohibition of investment in certain sectors is not only a government control measure but also a way to protect national interests. Prohibited sectors are often directly related to social ethics, public safety, the environment, or national defense. By clearly defining which areas are off-limits for investment, the government helps investors direct their business strategies more appropriately, ensuring sustainable development for both businesses and the economy.
Legal Basis for Identifying Prohibited Investment Sectors
Currently, the prohibited investment sectors in Vietnam are clearly defined in the 2020 Investment Law and are further detailed by Decree No. 31/2021/ND-CP. In addition, some sectors are also influenced by international agreements that Vietnam is a member of, such as CPTPP, EVFTA, and others. These legal documents serve as an important basis for investors to look up, assess, and determine whether the sector they are interested in is open for investment.
Prohibited Investment Sectors for Foreign Investors
For foreign investors, in addition to the general list of prohibited sectors, there is a specific category called “sectors not yet open to the market.” This special list applies only to foreign investors and entities with foreign direct investment (FDI) and reflects Vietnam’s controlled openness to foreign capital. These sectors may include public administration services, national security, defense, and state monopoly areas. Understanding this distinction helps foreign investors avoid unintentional mistakes when choosing their investment sectors.

2. What is the list of prohibited investment sectors in Vietnam?
General Prohibited Investment Sectors under the 2020 Investment Law
According to Article 6 of the 2020 Investment Law, certain sectors are completely prohibited for investment by any party, including: the business of narcotic substances, prostitution, human trafficking and the sale of human organs, activities related to human cloning, the business of fireworks, and debt collection services. These sectors are considered dangerous to society, violating ethics, national security, or public order, and thus are strictly prohibited. No individual or organization, whether domestic or foreign, is allowed to invest in these sectors in Vietnam.
Prohibited Investment Sectors for Foreign Investors (FDI)
In addition to the general prohibited sectors, foreign investors must also comply with the list of “sectors not yet open to the market” as specified in Decree 31/2021/ND-CP. This list includes sectors that Vietnamese law and international commitments do not permit foreign investors to engage in, such as: media, investigation services, fisheries exploitation, public postal services, or certain types of legal services, notary services, and technical safety inspection services in specialized sectors. The purpose of these regulations is to protect national interests, political security, and the stability of the economy.
Sectors Affecting National Defense and Security Prohibited for Investment
This category includes sectors that the government strictly controls and prohibits investment in because they are directly related to national security and strategic interests. These include the production and trading of weapons, military technical equipment, security and investigation services, military transportation vehicle inspections, and the production of specialized national defense equipment. These sectors can only be conducted by state-run organizations. The restriction of FDI in these sectors ensures national sovereignty, independence, and internal control.
State-Monopoly Sectors Prohibited for Investment
Apart from sectors prohibited for reasons of security or ethics, there are certain sectors that are state-monopolized and managed directly by the government. Examples include the issuance of national postage stamps, the production of gold bars, national television broadcasting, and the operation of the national electricity system. These sectors are not open to the private sector, whether domestic or foreign investors, to ensure that essential and strategic services are continuously and stably provided in line with the government’s development direction.
3. Impact of Prohibited Investment Sectors on Foreign Direct Investment (FDI)
Legal Risks of Violating Prohibited Investment Regulations
Investing in prohibited sectors can lead to serious consequences, including the revocation of the investment registration certificate, suspension of operations, or heavy administrative fines. In some severe cases, investors may face criminal prosecution if the investment activities are considered criminal violations. Additionally, violations can negatively impact the company’s reputation and make it more difficult to access new projects or markets in the future.
Forms of Sanctions for Investing in Prohibited Sectors
According to legal regulations, investors who violate these rules may face penalties ranging from warnings and fines of up to hundreds of millions of VND, to the revocation of business licenses and expulsion from Vietnam for foreign investors. Moreover, compensating for damages arising from illegal investment activities is also a potential risk, significantly increasing the costs and risks associated with the project.
Solutions to Avoid Violating Prohibited Investment Sectors
The optimal solution is for investors to carefully study the current legal regulations, particularly the Investment Law 2020 and Decree 31/2021/ND-CP. Before registering business sectors, it is advisable to consult legal experts or experienced agencies to clearly identify whether the intended investment sector is on the prohibited list. This helps save time, costs, and ensures that the investment plan proceeds smoothly.
Important Legal Considerations When Choosing an FDI Sector
Foreign investors need to pay special attention to regulations concerning prohibited sectors, sectors with conditions, and sectors with limited market access. Additionally, they should stay updated on the latest changes in investment laws and commitments under international agreements to which Vietnam is a party. Selecting the right sector not only ensures legal compliance but also enhances the chances of success and sustainable development for the FDI project.
4. The Process of Identifying Prohibited Investment Sectors for Foreign Investment
How to Search for the List of Prohibited Sectors
Foreign investors can search for the list of prohibited investment sectors on the National Business Registration Portal, through the Vietnamese legal system such as the Investment Law 2020, or directly through Decree 31/2021/ND-CP. This list is regularly updated to reflect changes in government management policies and international integration commitments. Proactively searching this list helps investors clearly identify whether the sector they intend to invest in is prohibited or restricted.
The Role of Regulatory Authorities in Identifying Prohibited Sectors
The Ministry of Planning and Investment is the primary agency responsible for publishing, explaining, and updating the list of prohibited sectors. Additionally, other relevant ministries, such as the Ministry of Industry and Trade, the Ministry of National Defense, and the Ministry of Public Security, play important roles in evaluating and providing expert opinions on the legality of specific investment projects. This coordination mechanism ensures transparency and consistency in the investment process.
International Agreements Vietnam Participates in Affecting Prohibited Sectors
Vietnam is currently a member of several new-generation free trade agreements, such as CPTPP, EVFTA, RCEP, etc. These agreements contain market opening commitments and sectoral exceptions, which directly influence the list of prohibited sectors or sectors “not yet open to the market.” Therefore, investors need to understand international commitments to avoid choosing sectors that are contrary to the announced policies.
Recent Changes to Prohibited Investment Sectors
In recent years, the list of prohibited investment sectors has been significantly shortened to align with the goal of improving the investment environment and international integration. The Investment Law 2020 and Decree 31/2021/ND-CP are important legal documents marking this progress. Foreign investors need to regularly update these changes through official sources and support from consulting agencies to ensure compliance with the law in all their investment activities in Vietnam.
Understanding the list of prohibited investment sectors is crucial for the success and risk mitigation of foreign direct investment (FDI) in Vietnam. Legal regulations are continuously updated and changed, so investors need to keep monitoring these developments to ensure the legality of their business operations. Using professional legal consulting services not only helps foreign investors clearly identify restricted sectors but also maximizes their support throughout the process of completing necessary legal procedures, safeguarding their interests, and optimizing investment effectiveness in the Vietnamese market.
