This is the best summary I could come up with:

Tensions over Russia’s war in Ukraine have hampered the ability of diplomats meeting in the United Arab Emirates for this year’s summit, known as COP28, to find a location for 2024.

The latest impasse came on Friday when Azerbaijan won the blessing of its neighbor and longtime foe, Armenia, to host the summit — only to be blocked by Russia hours later, according to European diplomats.

Observers called the inability of nations to select a host for next year a troubling sign for efforts to find global consensus on the far more serious issue of tackling climate change.

“Russia just wants to be a troublemaker on everything in the international setting,” said Jake Schmidt, the senior strategic director for the Natural Resources Defense Council, an environmental group.

Most Eastern European countries have strongly condemned Russia’s aggression against Ukraine and have joined Western powers in imposing stiff sanctions in response to the invasion.

Sultan Al Jaber, the Emirati oil executive who is presiding over the summit and has been widely criticized by environmental activists, has indicated that he is not eager to take on the mantle again, according to one person familiar with his thinking.
