Australian Prime Minister Scott Morrison vowed on Friday to press ahead with laws to require Facebook Inc to pay news outlets for content, saying he had received support from world leaders after the social media giant blacked out all media.

Facebook stripped the pages of domestic and foreign news outlets for Australians and blocked users of its platform from sharing any news content on Thursday, saying it had been left with no choice ahead of the new content laws.

The move, which also erased several state government and emergency department accounts, as well as nonprofit charity sites, caused outrage.

Morrison, who blasted Facebook on its own platform for "unfriending" Australia, said on Friday the leaders of Britain, Canada, France and India had shown support.

"There is a lot of world interest in what Australia is doing," Morrison told reporters in Sydney.

"That is why I invite ... Facebook to constructively engage because they know that what Australia will do here is likely to be followed by many other Western jurisdictions."

The Australian law, which will require Facebook and Google to reach commercial deals with Australian publishers or face compulsory arbitration, has already been cleared by the federal lower house and is expected to be passed by the Senate within the next week.

Australian Treasurer Josh Frydenberg said he had spoken to Facebook CEO Mark Zuckerberg for a second time following the news blackout.

"We talked through their remaining issues and agreed our respective teams would work through them immediately. We'll talk again over the weekend," Frydenberg said in a tweet.

In its statement announcing the move in Australia, Facebook said the Australian law "misunderstood" its value to publishers. Frydenberg earlier told the Australian Broadcasting Corp that "there is something much bigger here at stake than just one or two commercial deals. This is about Australia's sovereignty."

Facebook and Alphabet Inc owned Google had campaigned together against the laws with both threatening to withdraw key services from Australia if the laws took effect.

Google, however, announced a host of preemptive licencing deals over the past week, including a global agreement with Rupert Murdoch's News Corp, an American mass media and publishing company, in response to the regulatory push.

Facebook restored some government pages later on Thursday, but several charity, nonprofit and even neighborhood groups remained dark.

Australia's competition watchdog has maintained that for every $100 spent on online advertising, Google captures $53, Facebook takes $28 and the rest is shared among others, depriving media outlets of needed revenue to support journalism.
