Negotiations on prisoner swaps would also continue, Peskov said.
He did not provide a reason for why the peace negotiations, which U.S. President Donald Trump launched soon after he entered the White House, have hit a roadblock.
The last time the three parties met was in February in Geneva. A new round of talks scheduled for March 5 in Abu Dhabi was postponed indefinitely, days after the U.S. and Israel launched an attack on Iran, which has spilled over into the wider region.
In an interview with the BBC earlier this week, Ukraine’s President Volodymyr Zelenskyy said he had a “very bad feeling” about the effect of the events in Iran on the war in Ukraine.
Negotiations, he said, were “constantly being postponed. There is one reason: [the] war in Iran.”
The Ukrainian president was backed by British Prime Minister Keir Starmer who, after hosting Zelenskyy in London earlier this week, cautioned that, as the conflict in Iran and the Middle East unfolds, “we can’t lose focus on what’s going on in Ukraine and the need for our support.”
Russia, meanwhile, is already reaping some benefits from the Iran crisis, as higher oil prices are boosting its energy revenues while shifting international attention away from its onslaught against Ukraine.
