On November 17, 2025, Australian Prime Minister Anthony Albanese declared that Australia will not participate as a co-host for the COP31 climate summit alongside Turkiye. He explained that the rules of the United Nations Framework Convention on Climate Change (UNFCCC) do not allow for co-hosting arrangements. This announcement comes amid a backdrop of ongoing tensions between Australia and Turkiye. Albanese's comments were made during a press briefing, where he reiterated that the option of co-hosting had been clearly ruled out. The decision reflects the complexities of international climate negotiations and the diplomatic relations between the two nations.
