Scott Morrison denied one-on-one with Joe Biden as Boris Johnson joins meeting

Scott Morrison has met with Joe Biden on the sidelines of the G7 summit and agreed to work closely on challenges in the increasingly contested Indo-Pacific region including China.

Regional issues dominated the Australian prime minister's first face-to-face meeting with the US president late on Saturday - but the British prime minister, Boris Johnson, also attended in what became a trilateral engagement.
