Vietnam army hires censors to fight 'internet chaos'
The Vietnamese military has built up a force of more than 10,000 internet censors, according to local reports.
A People's Army leader is quoted as having said that the "cyber-troops" had been tasked with tackling "wrongful views" and anti-state propaganda.
Vietnam has a high rate of social media use but also a reputation for restricting freedom of speech.
In recent years, several bloggers have been jailed for publishing articles critical of the Communist state.
The latest revelation has led to comparisons with China, although Vietnam has been more willing to allow western tech firms to operate locally.
Lieutenant General Nguyen Trong Nghia - deputy head of the military's political department - is reported to have announced the existence of Force 47 at a speech in Hanoi on Christmas Day.
He is said to have declared that 62.7% of the Vietnam's population of more than 90 million citizens now had access to the net.
"Such a strong growth rate does both good and harm to the country," he said.
"On the negative side, the enemy takes advantage of the internet to create chaos."
Vietnam enforces a ban on independent political parties and human rights organisations.
In 2013, it introduced a law banning the public from discussing current affairs online, ordering that the use of social media and blogs was restricted to sharing personal information.
Despite this, the country ranks among Facebook's top 10 biggest markets, with about 52 million active users, as of August.
YouTube and Twitter are also popular in the nation.
Earlier this year, a draft cyber-security law was published that proposed popular tech companies would have to host local users' records within data servers based within its borders.
However, it was reported at the time that the proposal might clash with Vietnam's commitments to the World Trade Organisation.
The announcement about the censors preceded a court ruling in which 15 people were jailed for plotting to bomb the country's biggest airport.
The government's official news site said the accused had been directed by an overseas group that had used social media to recruit them and to spread propaganda.
Campaign groups have, however, criticised other arrests for internet-related dissent.
In November, Reporters Without Borders protested against the jailing of a 22-year-old blogger for disseminating "reactionary propaganda" via Facebook.
The group said the main reason for Nguyen Van Hoa's seven year sentence had been his coverage of a toxic spill from a steel plant that had poisoned millions of fish.
It has also drawn attention to Nguyen Ngoc Nhu Quynh, a blogger nicknamed Mother Mushroom, who was imprisoned for 10 years in June for criticising the handling of the same incident.
Human Rights Watch had previously reported that the number of bloggers and activists known to have been convicted and sentenced to prison in Vietnam had roughly tripled from 2015 to 2016, to at least 19 people.
