When Do Vietnam Cooperate with Foreign Authorities in Criminal Cases?

Are you or your loved one a foreigner being investigated in Vietnam? Are you worried that the case may expand across multiple countries or involve foreign authorities? When does international cooperation happen—and how could it affect your legal rights?

When Do Vietnamese Investigation Authorities Cooperate with Foreign Agencies?

In the context of globalization, criminal cases involving foreign elements are becoming increasingly common. Many clients of DEDICA Law—especially foreign nationals—have experienced anxiety upon learning that their cases may involve multiple jurisdictions.

However, not every case involves foreign authorities. Vietnamese law clearly defines when international cooperation in criminal proceedings is required, and such cooperation is always conducted under strict legal procedures.

Typical Situations Requiring International Cooperation

Under the 2015 Criminal Procedure Code of Vietnam and relevant international treaties, Vietnamese authorities may cooperate with foreign agencies in the following cases:

1. Cases with Clear Foreign Elements

• The accused is a foreign national
• The victim is a foreign national
• The criminal act spans multiple countries

Example: A foreign individual commits fraud in Vietnam, but the funds are transferred through bank accounts in another country.

2. Need to Collect Evidence Abroad

In many cases, key evidence may be located outside Vietnam, such as:

• Bank accounts
• Emails or digital data
• Witness testimonies

In such situations, Vietnamese authorities may issue a mutual legal assistance request to foreign jurisdictions.

3. Arrest or Extradition of Suspects

If a suspect has left Vietnam, authorities may:

• Issue an international arrest warrant
• Request extradition under bilateral or multilateral treaties

4. Freezing Assets Overseas

In cases involving economic crimes, corruption, or money laundering, cross-border asset tracing and freezing are common.

Forms of Cooperation Between Vietnam and Foreign Authorities

International cooperation is not arbitrary—it must follow specific legal mechanisms:

Mutual Legal Assistance in Criminal Matters

This is the most common form:

• Vietnam sends an official request to another country
• That country carries out actions such as collecting evidence or taking statements

Judicial Assistance Treaties

Vietnam has signed multiple agreements with other countries, providing a legal framework for cooperation.

Through INTERPOL

In international manhunt cases, Vietnamese authorities may coordinate through the International Criminal Police Organization (INTERPOL).

How Does International Cooperation Affect Foreigners in Criminal Cases?

If you are a foreign national under investigation or involved in a criminal case in Vietnam, the presence of international cooperation can increase your concerns. However, understanding the process will help you better protect your rights.

The Process May Be Longer and More Complex

Compared to domestic cases, cross-border cases often:

• Take longer due to waiting for responses from foreign authorities
• Involve multiple agencies

This may impact:

• Investigation timelines
• Legal procedures

However, this does not necessarily mean a worse outcome.

Your Legal Rights Are Still Protected

Even in international cases, your rights under Vietnamese law remain protected:

• The right to a defense lawyer
• The right to an interpreter
• The right to notify your consulate

Under the Vienna Convention on Consular Relations, detained foreign nationals have the right to contact their diplomatic representatives.

Key Risks You Should Be Aware Of

In practice, DEDICA Law has seen many clients who:

• Do not fully understand Vietnam’s legal system
• Provide inaccurate information due to language barriers
• Become unprepared when investigations expand internationally

These mistakes can significantly affect defense strategies.
