EU’s hopes of US increasing pressure on Kremlin have been dashed, and Hungary could yet make situation worse

European leaders – who have promised to impose “massive” new sanctions on Russia after Vladimir Putin’s rejection of a ceasefire in Ukraine – face the prospect of having to introduce their planned expansion of economic restrictions on the Russian war economy without the United States.

European hopes that Donald Trump might increase the pressure on the Kremlin were dashed after the US president’s two-hour inconclusive phone call with Putin on Monday. Trump did not follow through on previous threats to introduce “large-scale” sanctions on Russia if there was no ceasefire, but instead extolled the prospect of restarting trade with Moscow.
