Azerbaijan is tipped to host next year's UN climate summit after striking a deal with longtime adversary Armenia over its bid. Diplomatic sources told Reuters the Azerbaijani bid looked set to win support from other nations, though the issue is still being negotiated at the COP28 climate summit in Dubai. The decision about who will take over from current COP28 host, the U.A.E., has been in an unprecedented geopolitical deadlock after Russia said it would veto any EU country's bid. Azerbaijan confirmed on December 7 that it had struck a deal with Armenia that allows Baku to bid to host the talks.
