Facebook is a popular platform for activists in Vietnam, where all independent media is banned, but the company confirmed in a statement to AFP that it had been instructed by Hanoi to restrict access to content "deemed to be illegal". "We have taken this action to ensure our services remain available and usable for millions of people in Vietnam, who rely on them every day," a spokesperson said. But Amnesty said the decision was "a devastating turning point for freedom of expression" in the country.
"Ruthless suppression of freedom of expression is nothing new, but Facebook's shift in policy makes them complicit," said the rights watchdog's William Nee.
More than 53 million people in Vietnam - over half the population - use Facebook. The platform is also a crucial marketing tool for local business.
