Ukrainian President Volodymyr Zelensky on Tuesday urged NATO to speed up his country’s membership plan, saying a signal needed to be sent to Russia as tensions rise between the neighbours.In a tweet to NATO Secretary General Jens Stoltenberg after the two spoke by phone, Zelensky said Kiev was committed to defence reforms requested by the alliance to agree a Membership Action Plan (MAP) for Ukraine.”But reforms alone will not stop Russia,” Zelensky said. “NATO is the only way to end the war in Donbas. Ukraine’s MAP will be a real signal for Russia.”
