HomeLegal basis: Thailand and Vietnam signed a bilateral extradition treaty in 2015, which entered into force and established formal procedures for surrender between the two states. The treaty requires dual criminality, sets a minimum sentence threshold, and provides for the political offence exception. Geographic proximity and active police cooperation — including joint drug enforcement — make this a high-activity extradition corridor.
Vietnam applies a civil law system with significant party influence over judicial proceedings. Extradition requests involving drug trafficking — particularly narcotics sourced from the Golden Triangle — receive priority handling. The death penalty is applicable in Vietnam for a range of serious offences, including drug trafficking, which requires a formal assurance against execution as a condition of extradition under Thai law. Vietnamese nationals face expedited proceedings in drug cases given bilateral law enforcement cooperation.
The treaty creates a formal extradition pathway with established timelines and procedural rights. A person detained in Thailand on a Vietnamese request has the right to challenge dual criminality, raise the political offence exception, and seek assurance against the death penalty where applicable. Legal intervention at the stage of provisional detention — before any formal extradition hearing — provides the most options for a successful defence.

Facing Cross-Border Legal Threats? Protect Your Rights Early
Extradition procedures and Interpol notices involve complex international mechanisms where tactical timing is critical. Acting before an arrest opens the widest window for building a proactive defense, analyzing double criminality, and challenging abusive alerts.
Overview of Thailand–Vietnam Extradition
Thailand and Vietnam do not have a bilateral extradition treaty in place. Without a formal extradition agreement between the two countries, any extradition requests must be handled through alternative legal mechanisms and diplomatic channels, which can significantly complicate the process for both requesting and requested parties.
Short answer: Thailand and Vietnam have a bilateral extradition treaty supported by ASEAN Mutual Legal Assistance Treaty cooperation. Both countries have significant shared concerns around drug trafficking along the Greater Mekong Subregion routes, which drives a substantial share of extradition activity between them.
In the absence of a bilateral treaty, extradition between Thailand and Vietnam may still be possible on the basis of reciprocity under Thailand’s Extradition Act B.E. 2551 (2008). The legal framework governing extradition in Thailand includes standard principles such as double criminality (requiring a minimum penalty of one year), the rule of speciality, and the political offence exception. Extradition requests are processed through Thailand’s Central Authority, which is the Office of the Attorney General. Thai nationals are generally not extradited unless specific treaty provisions permit it or with explicit consent and Cabinet approval. Given the lack of a formal treaty, any extradition proceedings would rely on reciprocity arrangements and diplomatic negotiations between the two nations.
Does Thailand Have an Extradition Treaty with Vietnam?
- Treaty status: No
- Sources: Requests go via Thailand’s Central Authority (Office of the Attorney General). Double criminality (min. 1 year penalty), rule of speciality, political offence exception. Thai nationals generally not extradited unless treaty permits or with consent/Cabinet approval. If no treaty, possible on reciprocity under Extradition Act B.E. 2551 (2008). No bilateral treaty; reciprocity possible.
Thailand and Vietnam do not have a bilateral extradition treaty in place. Despite their geographical proximity and shared borders in the Southeast Asian region, the two countries have not established a formal extradition agreement to facilitate the transfer of fugitives between their jurisdictions.
In the absence of a bilateral treaty, extradition between Thailand and Vietnam may still be possible through the principle of reciprocity under Thailand’s Extradition Act B.E. 2551 (2008). This means that extradition requests can be considered on a case-by-case basis, provided that both countries agree to cooperate and that the standard extradition requirements are met.
Any extradition requests between the two countries would need to go through Thailand’s Central Authority, which is the Office of the Attorney General. The standard requirements would apply, including double criminality (the offense must be punishable by at least one year in both countries), the rule of specialty, and the political offense exception.
Thai nationals are generally not extradited unless specifically permitted by treaty or with explicit consent and Cabinet approval. Given the absence of a formal treaty with Vietnam, the extradition of Thai nationals would require special governmental approval and would be subject to additional scrutiny.
The lack of a formal extradition treaty between Thailand and Vietnam reflects the complex diplomatic and legal relationships in the region, where countries may rely on alternative mechanisms for international cooperation in criminal matters.
Extradition Process from Thailand to Vietnam
Extradition requests from Vietnam to Thailand are typically initiated by Vietnamese law enforcement agencies or the Vietnamese Ministry of Public Security through diplomatic channels. The request is first received by Thailand’s Ministry of Foreign Affairs, which forwards it to the Office of the Attorney General for legal review. The Thai Attorney General’s Office conducts an initial assessment to determine whether the request meets the formal requirements under Thai law and any applicable bilateral agreements between the two countries.
Once the preliminary review is completed, the case proceeds to the Thai court system for judicial examination. The Criminal Court has jurisdiction over extradition matters and conducts hearings to evaluate the evidence presented by the requesting state. The court examines whether the alleged crimes constitute extraditable offenses under Thai law, whether there is sufficient evidence to support the charges, and whether any legal barriers to extradition exist. The requested person has the right to legal representation and can present defenses against extradition during these proceedings.
The entire extradition process from Thailand to Vietnam typically takes between 6 to 18 months, depending on the complexity of the case and whether appeals are filed. Simple cases with clear evidence and no legal complications may be resolved within 6-8 months, while complex cases involving multiple charges or legal challenges can extend beyond a year. The timeline can be further affected by the quality of documentation provided by Vietnam and the availability of court schedules.
