The leaders of the US, India, Australia and Japan have cancelled their Quad summit after American President Joe Biden called off his trip to Sydney due to domestic issues.
They are instead expected to meet on the sidelines of the G7 summit in Japan in June.
Mr Biden was scheduled to travel to Australia, with a stop in Papua New Guinea, for the May 24 Quad summit.
But Australian Prime Minister Anthony Albenese said on Wednesday that Mr Biden had cancelled the trip.
Indian Prime Minister Narendra Modi has been invited to the G7 summit, taking place in Hiroshima from June 19 to 21, as a guest by his Japanese counterpart Kishida Fumio.
The Quadrilateral Security Dialogue, commonly known as the Quad, is a loose strategic alliance between the US, India, Australia and Japan.
The G7 includes the US, Canada, France, Germany, Italy, Japan and the UK.
Russia was part of the forum until 2014 when it was suspended following its annexation of Ukraine’s Crimea region.
The group meets annually to discuss global issues. The summit is under Japan’s presidency this year.
