Iranian Foreign Ministry spokesman Seyyed Abbas Mousavi congratulated the Ukrainian president and people over the successful holding of presidential elections in the country.
Volodymyr Zelensky won the landslide victory in Ukraine's presidential election on Sunday, drawing congratulations from global leaders while dealing a stunning rebuke to his country's political establishment.
Mousavi said winning the majority of votes by Zelensky in the elections indicates high public confidence in him, according to the Foreign Ministry’s official website.
He expressed hope that the developments in Ukraine would lead to success and sustainable peace in the European country as well as further expansion of Iran-Ukraine relations.
Zelensky trounced incumbent Petro Poroshenko by taking 73 percent of the vote, according to partial official results.
Poroshenko garnered just 24 percent, losing to the 41-year-old across the country, with 42 percent of ballots counted, AFP reported.
It was an extraordinary outcome to a campaign that started as a joke but struck a chord with voters frustrated by social injustice, corruption and a war with separatists in eastern Ukraine that has claimed some 13,000 lives.
The star of the TV series "Servant of the People" will now take the helm of a country of 45 million people beset by challenges and having run on the vaguest of political platforms.
"I will never let you down," Zelensky told jubilant supporters at his campaign headquarters where he was showered with glittering confetti.
Exit polls showed Zelensky took 87 percent of the vote in eastern Ukraine and defeated Poroshenko even in the west, where the incumbent traditionally enjoyed strong support.
Poroshenko, 53, said the results were clear and enough reason to "call my opponent and congratulate him".
"I will leave office but I want to firmly stress – I will not quit politics," Poroshenko said in a speech at his campaign headquarters, where supporters clapped, cried and chanted "thank you" to the outgoing leader.
He also appealed to the international community to help safeguard Ukraine's pro-Western course.
"We realize that the Kremlin might be enjoying the election result," he said.
Zelensky said he wanted to "reboot" Western-brokered peace talks that have so far failed to end the conflict.
Moscow said the vote result showed Ukrainians wanted "change".
The outgoing leader came to power after a 2014 pro-Western protests ousted a Kremlin-backed government.
