BRUSSELS, March 1 (Reuters) - NATO chief Mark Rutte said on Saturday he told Ukrainian President Volodymyr Zelenskiy that he needs to find a way to restore his relationship with U.S. President Donald Trump after their clash at a White House meeting on Friday.

The confrontation flared over differing visions of how to end Russia’s three-year-old invasion, with Zelenskiy seeking strong security guarantees from a Trump administration that has embraced diplomacy with Vladimir Putin’s Russia.

The meeting, which Rutte described as “unfortunate”, plunged ties between Kyiv and its top military backer to a new low. “I said: I think you have to find a way, dear Volodymyr, to restore your relationship with Donald Trump and the American administration. That is important going forward,” Rutte told the BBC, commenting on a call he had with Zelenskiy on Friday.
