The United States has snubbed the Christchurch Call tech pledge, saying it endorses the overall goals of the pledge but can not sign onto it. She wrote an opinion piece for The New York Times in which she said social media needs to find a balance between freedom and broadcasting terrorism.
"As an industry, tech companies created new services to bring out the best - not the worst - in people", Smith wrote.
After much speculation, Facebook has imposed restrictions on live-streaming following the New Zealand attacks in March. Following the Christchurch shooting, Facebook (FB) removed 1.5 million copies of the mosque attack video.
The distribution of "extremist" content will now be expressly prohibited by the terms and conditions of use agreements which users must agree before using the platforms.
The Christchurch Call "is a global response to a tragedy that occurred on the shores of my country but was ultimately felt around the world", said New Zealand Prime Minister Jacinta Ardern, who has played a leading role pushing for globally coordinated efforts to eliminate online extremism.
Other world leaders took part in the summit including Justin Trudeau of Canda (centre) and Theresa May of the United Kingdom (right).
The group includes 55 funds, including 27 from New Zealand and 28 global funds, and includes Crown-owned investors the New Zealand Super Fund, Accident Compensation Corporation, the Government Superannuation Fund, the National Provident Fund and Kiwi Wealth.
In an email to Reuters, Ardern called Facebook's new limits on live streaming "a good first step to restrict the application being used as a tool for terrorists".
NZ Super Fund chief executive Matt Whineray said they expected to see stronger controls from tech companies to prevent objectionable content being posted online. But the White House said in a statement it is "not now in a position to join the endorsement", which leaders from countries such as Australia, Canada and the United Kingdom are expected to sign. "Social media companies will be left with the thorny task of deciding what constitutes violent extremist content, since it is not defined in the accord".
It also said it would fund research at three universities on techniques to detect manipulated media, which Facebook's systems struggled to spot in the aftermath of the Christchurch attacks. "And so we must ensure that in our attempts to prevent harm that we do not compromise the integral pillar of society that is freedom of expression", she wrote.
The Trump administration has been involved in efforts to end online terrorist content, including its September 2017 endorsement of the Zurich-London Recommendations on Preventing and Countering Violent Extremism and Terrorism Online.
