Authorities in Vietnam are pressing on with a crackdown on social media users who are seen as critical of the government, using two articles of the Criminal Code that rights groups say are too vague, to punish those “opposing” the state and the ruling Communist Party.

After seven months in pre-trial detention, authorities in Hanoi have announced plans to prosecute Facebooker Phan Van Bach under Article 117 of the Criminal Code for "making, storing, spreading information, materials, items for the purpose of opposing the State of Socialist Republic of Vietnam.”

Bach, 49, has been an active campaigner for more a decade. He took part in protests against China’s territorial claims in the South China Sea in 2011, the Green Trees environmental demonstrations in 2015, and the protests against pollution caused by Formosa Plastics in 2016.

According to an indictment issued on July 19 and recently shared by his family, Bach is accused of using his personal Facebook account to post 12 articles and six video clips between 2018 and 2022 with content said to "distort the Party's policies and guidelines, defame the Socialist Republic of Vietnam, deny the leadership role of the Communist Party of Vietnam, and disseminate edited images that defame state leaders and incite the masses."

Bach was detained on Dec. 29, 2023, but his wife Nguyen Thi Yeu wasn't allowed to see him until June 4.

“I didn't recognize him at all. He was no longer the same person as when he left,” she told Radio Free Asia. “He was thin and had scabies all over his body.”

Her husband told her he had diarrhea as soon as he was taken to the detention camp. When he asked to go to the hospital for treatment, he was given medicine, which made him constipated.

He was put in a 40 square meter (431 square foot) cell with more than 30 other inmates, where he developed scabies.

RFA called the investigator who handled Bach’s case several times but he did not answer the telephone.

‘Propaganda against the state’

In 2017, Bach joined independent YouTube channel CHTV, reporting on Vietnam's socio-economic issues.

Three members of the channel, Vu Quang Thuan, Le Van Dung and Le Trong Hung, are serving prison sentences ranging from five to eight years for the crime of “propaganda against the state.”

Bach often hosted live talks criticizing Vietnam’s one-party regime but in 2018 he announced he was leaving CHTV.

His Facebook page shows that in recent years he has only focused on his labor export business.
