The UN rights chief warned Wednesday that China and other Asian countries were using the coronavirus crisis as an excuse to clamp down on free expression and tighten censorship.
In a statement, Michelle Bachelet expressed alarm over how censorship had been tightened in several countries, along with arbitrary arrests and detention of people who criticise their government's response, or even who simply share information or views on the pandemic.
"Arrests for expressing discontent or allegedly spreading false information through the press and social media, have been reported in Bangladesh, Cambodia, China, India, Indonesia, Malaysia, Myanmar, Nepal, the Philippines, Sri Lanka, Thailand and Vietnam," the statement said.
The UN High Commissioner said she recognised the need to restrict harmful disinformation to protect public health, or any incitement of hatred towards minority groups.
But she insisted that this should not result in purposeful or unintentional censorship. "
"While governments may have a legitimate interest in controlling the spread of misinformation in a volatile and sensitive context, this must be proportionate and protect freedom of expression," Bachelet said.
"This crisis should not be used to restrict dissent or the free flow of information and debate," she said.
Her statement listed problems in each of the Asian countries identified.
For China, the UN rights office said it had received information on "more than a dozen cases of medical professionals, academics and ordinary citizens who appear to have been detained, and in some instances charged, for publishing their views or other information on the situation related to COVID-19," or for being critical of the government's response to the crisis.
"These cases include two young graduate students who were reportedly detained in April after setting up an online repository of web content related to the COVID-19 outbreak in China," it said.
In India, meanwhile, it pointed out that several journalists and at least one doctor had been charged for their public criticism of the authorities' response to the crisis.
And in Indonesia at least 51 people were reportedly being investigated under the criminal defamation law for allegedly spreading "fake news" on the pandemic.
In Cambodia meanwhile, the rights office said it had documented the arrest of 30 people, including a 14-year-old girl, for COVID-19 related public comments and social media posts.
In Vietnam, authorities reported that over 600 Facebook users have been summoned for questioning relating to online posts about the virus.
