Russia seized the Ukrainian vessels and their crews on Sunday near Crimea, the Ukrainian region which Moscow annexed in 2014, over what it said was their illegal entry into Russian waters, which Ukraine denies. Some of Ukraine’s Western allies have also raised the possibility of imposing new sanctions on Russia over the episode, which could deliver a blow to the Russian economy. Putin said he also still hoped to meet Trump at the G20, while the Kremlin said the meeting was still being prepared and Washington had not informed Moscow it was off.
