EU Leaders Meet for So-called Summit of Gloom Jamie Dettmer It has been dubbed the summit of gloom. For the next two days, the European Union's 27 national leaders will meet in Brussels and try to reach agreement on a series of thorny issues, from the bloc's future trading relationship with post-Brexit Britain to an ambitious climate action plan to reduce carbon emissions and achieve "climate neutrality" by 2050. They will also discuss how to coordinate the bloc's coronavirus pandemic response. Breakthroughs on all of these issues are not likely. The EU's increasingly fraught relations with Russia and Turkey will also be discussed. Navalny poisoning On the eve of the summit, Russia threatened to break ties with the bloc amid an intensifying diplomatic dispute over the poisoning of Alexei Navalny, President Vladimir Putin's biggest domestic foe. Sergey Lavrov, Russia's foreign minister, issued the warning after the EU's top diplomats agreed Monday to impose new sanctions on Moscow in response to the alleged Kremlin-sponsored plot to kill Navalny. The Kremlin has denied any involvement in the poisoning. First up on the agenda will be a discussion about the bloc's future relations with Britain -- and the failure so far to reach consensus on a post-Brexit trade deal. Midweek, British Prime Minister Boris Johnson expressed "disappointment" at the lack of progress in the monthslong fractious talks among his aides and EU chief negotiator Michel Barnier. Disagreements over fishing rights in British territorial waters, security cooperation and limits on state subsidies to British business have all held up a deal. .
