US President Donald Trump has postponed this year's G7 summit until September, and signalled the need to include more countries.
"I'm postponing it because I don't feel that as a G7 it properly represents what's going on in the world," he said, adding that Australia, Russia, South Korea and India must be extended invitations to attend the event.
He called it a "very outdated group of countries" in its current format.
However, it's unclear whether his decision to expand the invitation list was a bid to permanently expand the G7, which currently includes the US, UK, France, Germany, Japan, Italy and Canada.
