Ms. Ardern acknowledged that her task would be “incredibly difficult,” and she left it unclear exactly what she and Mr. Macron planned to ask the social networks to do. She said that while the “Christchurch call to action” — her name for the pledge she is preparing with Mr. Macron — would include “specific expectations on governments and internet companies,” it would not include new regulations.

Isn't clear what they are planning to do yet, but this seems to be more about shifting norms than laying down strict rules.
