China has today passed a controversial cybersecurity bill, tightening restrictions on online freedom of speech.

The bill also imposes new rules on online service providers, raising concerns it is further cloistering its heavily controlled internet.

The legislation, passed by China's largely rubber-stamp parliament and set to take effect in June 2017, is an 'objective need' of China as a major internet power, a parliament official said.

Amnesty International, however, said it was 'draconian' measure that violates people's rights to freedom of expression and privacy.

China's new cybersecurity law requires companies to verify a user's identity, effectively making it illegal to go online anonymously

WHAT DOES THE BILL MEAN? The law is largely focused on protecting the country's networks and private user information. But it also bans internet users from publishing a wide variety of information, including anything that damages 'national honour', 'disturbs economic or social order' or is aimed at 'overthrowing the socialist system'.

The ruling Communist Party oversees a vast censorship system, dubbed the Great Firewall, that aggressively blocks sites or snuffs out internet content and commentary on topics considered sensitive, such as Beijing's human rights record and criticism of the government.

It has aggressively blocked major companies such as Google and Facebook from offering their services in its domestic cyber space.

The law, which was approved by the National People's Congress Standing Committee, is largely focused on protecting the country's networks and private user information.

The legislation drew a wave of criticism from rights groups and foreign business organisations, who said its vague language and overreaching security requirements would restrict freedom of speech and throw up barriers to global companies hoping to serve China's enormous market of more than 710 million internet users.

'This dangerous law commandeers internet companies to be de facto agents of the state, by requiring them to censor and provide personal data to the authorities at a whim,' said Patrick Poon, China researcher at global rights group Amnesty International.

James Zimmerman, chairman of the American Chamber of Commerce in China, said the law risks China 'becoming isolated technologically from the rest of the world'.

'Requirements for national security reviews and data sharing will unnecessarily weaken security and potentially expose personal information,' he wrote in a statement, adding that overall the new law 'creates barriers to trade and innovation'.

Concerns about the legislation were overblown, Zhao Zeliang, the director of China's Cyberspace Administration, told reporters.

The law is not intended 'to limit foreign technology or products or to put up trade barriers', he said.

'A few foreign friends, they equate 'security controls, voluntary controls, security trustworthiness' with trade protectionism,' he said, adding 'that's a type of misunderstanding. A type of prejudice.'

China's foreign ministry spokesman Lu Kang said there were 'no significant differences' between the new Chinese laws and laws of other countries', adding the law had involved a lengthy public comment period, making it 'more transparent than other governments in this regard'.

The European Chamber of Commerce disagreed, saying in a statement the 'overall lack of transparency over the last year surrounding this significant and wide-reaching piece of legislation has created a great deal of uncertainty and negativity in the business environment'.

Amnesty's Poon said the law 'goes further than ever before in codifying abusive practices, with a near-total disregard for the rights to freedom of expression and privacy.'

INTERNET CENSORSHIP AROUND THE WORLD The internet has revolutionised communication and promotes free speech across the globe. Consequently, online freedom is a hot topic. Some governments consider the internet to be dangerous and inflammatory so they regulate it. A firm called IVPN recently created a map of internet freedom around the world based on a Freedom House report in 2013. In the report, countries were reviewed on limits placed on online content, obstacles to Internet access, and violations of user rights. They were then graded as free, partly free or not free and marked on a map in white, pink and red respectively. Countries marked in grey were not included in the report. China, Iran and Syria were found to be the top three user rights violators when it comes to online freedom.

Chinese authorities have long reserved the right to control and censor online content.

The country stepped up controls in 2013, launching a wide-ranging internet crackdown.

Hundreds of Chinese bloggers and journalists were detained as part of the campaign, which has seen influential critics of Beijing paraded on state television.

Under regulations announced at the time, Chinese internet users face three years in prison for writing defamatory messages that are re-posted 500 times or more.

They can also be jailed if offending posts are viewed more than 5,000 times.

Comments posted on social media have been used in the prosecution of various activists, such as human rights lawyer Pu Zhiqiang.
