Vietnam's Ministry of Public Security has officially designated Nguyễn Văn Đài, a 57-year-old Vietnamese national currently living in Germany, as a terrorist. The ministry's announcement, made on October 7, cites legal frameworks both in Vietnam and internationally to support this classification.

Nguyễn Văn Đài, who is also known by the alias "Nguyễn Việt Hưng," has a history of political activism and has been involved with the Việt Tân organization, which the ministry has labeled as a terrorist group. The ministry's statement highlights Đài's role as a "central committee member" of this organization.

Đài has faced legal repercussions in Vietnam for his actions against the state. In 2007, he was sentenced to four years in prison followed by four years of house arrest for propaganda against the Socialist Republic of Vietnam, under Article 88 of the 1999 Penal Code. Later, in 2018, he received a harsher sentence of 15 years in prison and five years of house arrest for activities aimed at overthrowing the people's government.

Following these sentences, Đài was granted temporary suspension of his sentence and subsequently left for Germany. On December 5, 2025, the Ministry of Public Security issued a warrant for his arrest on charges of producing, storing, distributing, or propagating information and materials against the Socialist Republic of Vietnam, as per Article 117 of the Penal Code. By December 31, 2025, he was tried in absentia and sentenced to 17 years in prison and an additional five years of house arrest for the aforementioned charges.
