PHNOM PENH (REUTERS) - Cambodia's Parliament passed a law on Friday (April 10) to prepare the way for a state of emergency, which Prime Minister Hun Sen has said he might have to declare to reinforce the campaign against the coronavirus.

Human rights groups say an emergency would give sweeping powers to Mr Hun Sen, who Western countries have long condemned for crackdowns on opponents, civil rights groups and the media.

The law allows the government under an emergency to monitor communications, control media and social media, prohibit or restrict distribution of information that could generate public fear or unrest, or that could damage national security.

"The purpose of making this law for Cambodia is not unique, as there is this law already in many other democratic countries," said Ministry of Justice spokesman Chin Malin. "The law is intended to protect public order, security, people's interests, lives, health, property and the environment."

Cambodia reported one new coronavirus case on Friday, taking its confirmed tally to 119, the health ministry said.

Mr Hun Sen was initially sceptical about the threat posed by the coronavirus but cases have been increasing and in recent weeks the government has ordered restaurants, bars and casinos to close and limited entry visas for foreigners.

Mr Hun Sen has said he might need emergency powers to help stem the outbreak.

His party holds every seat in the 125-seat National Assembly and all members present voted to adopt the Law on Governing the Country in a State of Emergency.

Rights groups say the law contains broad and vague provisions that would violate fundamental rights and could be misused against critics.

It provides for prison terms of up to 10 years for anyone convicted of obstructing the authorities or not respecting government measures that leads to unrest or affects national security.

Mr Brad Adams, Asia director at Human Rights Watch, said Cambodia should be passing laws to protect public health, not using the coronavirus as an excuse to extend government powers.

"The Cambodian government is using the Covid-19 pandemic as a pretext to assert absolute power over all aspects of civil, political, social, and economic life - all without any time limits or checks on abuses of power," Mr Adams said in a statement.

The rights group Amnesty International said the law had been rammed through the legislative process with no transparency, no consultation and no due process.

"The idea of concentrating even more unchecked power into the hands of this government is worrying in the extreme," group official David Griffiths said.
