US President Donald Trump on Sunday defended the exemption of sanctions on Russian diesel, stating that the move was aimed at promoting peace talks in the Russia-Ukraine war, and accused Ukrainian President Volodymyr Zelenskyy of being unwilling to end the war. US Treasury Secretary Scott Bessent, meanwhile, warned Zelenskyy to be "very careful" about his claims regarding "US restrictions on Starlink," and criticized Zelenskyy's assertion that Ukraine must "win" as a "false dichotomy," arguing that the war must be resolved through negotiations.
