Prime Minister Justin Trudeau attended summit in Paris on May 15 co-chaired by French President Emmanuel Macron and New Zealand Prime Minister Jacinda Ardern, that urged to have world leaders and chiefs of tech companies sign the "Christchurch Call," a pledge to eliminate terrorist and violent extremist content online.
In an opinion piece in The New York Times on May 11, Ardern said the "Christchurch Call" will be a voluntary framework that commits signatories to put in place specific measures to prevent the uploading of terrorist content.
Heads of state of countries who also battled against militant extremism, such as Norway and Britain, joined the meeting.
Leaders of Jordan, Senegal, Indonesia and the European Commission were also present.
The meeting was held alongside the "Tech for Humanity" meeting of G7 Digital Ministers, of which France is the chair, and France's separate "Tech for Good" summit.
Representatives from Facebook, Google, Twitter and other tech companies are expected to be part of the meeting, although Facebook head Mark Zuckerberg will not be in attendance.
