REUTERSThe United States cancelled a planned Budapest summit between President Donald Trump and Russian President Vladimir Putin following Russia's firm stance on hardline demands regarding Ukraine, the Financial Times reported on Friday. The decision came after a tense call between the two countries' top diplomats, the Financial Times said, citing people familiar with the matter. Plans for a summit in Budapest this month between Trump and Putin were put on hold after Moscow stuck to demands, including that Ukraine cede more territory as a condition for a ceasefire. The US then cancelled the summit following a call between Russian Foreign Minister Sergei Lavrov and US Secretary of State Marco Rubio, after which Rubio told Trump that Moscow was showing no willingness to negotiate, the FT report added. Ukrainian President Volodymyr Zelensky said this month that while Ukraine is ready for peace talks, it will not withdraw its troops from additional territory first as Moscow demanded.
