Another source saying that the UAE planned to use the COP28 Climate talks to make oil deals.
Attempting to do business deals during the COP process appears to be a serious breach of the standards of conduct expected of a COP president.
Those standards are set by the UN body responsible for the climate negotiations, the United Nations Framework Convention on Climate Change (UNFCCC).
The UNFCCC says the "cardinal principle" for COP presidents and their teams is "the obligation of impartiality".
It told the BBC that COP presidents are "expected to act without bias, prejudice, favouritism, caprice, self-interest, preference or deference, strictly based on sound, independent and fair judgement".
"They are also expected to ensure that personal views and convictions do not compromise or appear to compromise their role and functions as a UNFCCC office," it continued.
Manuel Pulgar-Vidal, the head of the COP20 summit in Peru in 2014, worries a collapse in trust could mean no progress on tackling climate change in Dubai.
"The president of the COP is the leader of the world, is trying to build consensus on behalf of the planet," he told the BBC.
"If any president of the COP tries to bring a particular interest, [including] commercial interest, that could mean the failure of the COP."
