Vietnamese police detained a French dissident of Vietnamese descent for deportation on Friday after the Communist state revoked his Vietnamese citizenship last month, his wife said. Pham Minh Hoang, a 61-year-old activist and mathematics lecturer, had dual French and Vietnamese citizenship before Vietnam cancelled his citizenship without giving a reason, a move that drew criticism from human rights groups. Despite sweeping reforms to the economy and growing openness to social change, the Communist Party retains tight media censorship and tolerates no criticism. Dozens of bloggers and activists are serving sentences for crimes against the state. Hoang’s wife, Le Thi Kieu Oanh, said police came to their house in Ho Chi Minh city on Friday asking to carry out a regular check on their household registration but later forced Hoang to leave with them and said they would deport him the next day. Vietnamese dissidents beaten and harassed by ‘thugs’, according to Human Rights Watch “My husband refused to go but three to four police officers used violence to drag him out and locked me inside the house... They also parked a signal jammer car right in front of our house,” Oanh said. The French embassy in Vietnam said it had no immediate comment. Ho Chi Minh police said they could not provide any information on the case. Hoang was sentenced to three years in jail for attempted subversion in 2011 but was released after 17 months and served three years under house arrest. He frequently posts blogs criticising the Communist party regime and the Vietnamese government. Prominent Vietnamese blogger who wrote about police corruption flees to the US after jail release Oanh said they were informed by the French consul general on June 1 of Hoang’s Vietnamese citizenship being annulled and were given a month for him to leave the country but they refused to obey. “It’s Hoang’s ideal to stay in Vietnam to raise a voice and contribute to building freedom and democracy,” Oanh said. “After the signal jammer car left I called the consul general and he just said he acknowledged the situation. What they would do after that, I don’t know.” She also said the French embassy and consulate in Vietnam are waiting for guidance from the French foreign ministry’s decision on paper issuance for Hoang as he no longer has a Vietnamese or French passport, both of which have expired. Hanoi admits to army of 900 ‘internet public opinion shapers’ Vietnam’s foreign ministry spokeswoman Le Thi Thu Hang last week defended the decision to revoke Hoang’s citizenship, saying it was “conducted in accordance with the provisions of Vietnamese law.” Hoang is a member of California-based Viet Tan, a group Vietnam considers a terrorist organisation. “The French government should not take part in the Hanoi regime’s brazen exile of a well-known human rights activist,” Viet Tan said in a statement.
