Diplomatic tensions involving Cuba and the United States intensified during the 81st UN General Assembly. Following remarks by Donald Trump, who described Cuba as an ‘absolutely failed state’ and predicted the communist government ‘will fall,’ the Cuban delegation walked out of the assembly hall in protest. Cuban Foreign Minister Bruno Rodríguez rejected the comments as ‘lies and slanders,’ while President Miguel Díaz-Canel accused the U.S. of conducting a ‘genocidal economic war’ through energy blockades.
